MIL-STD810H method 524.1 freeze-thaw, CCK-T series climate chambers

The purpose of this freeze-thaw test method is to determine the material’s ability to withstand the effects of moisture phase changes between liquid and solid, in or on the material, as the ambient temperature passes through the freezing point and the effects of moisture induced by transfer from a cold to a warm environment or from a warm to a cold environment.

This method is applicable to materials that will be exposed to temperatures above the freezing point while wet or in the presence of moisture, to induce physical changes in the material and evaluate resistance to distortion or jamming of moving parts, failure of bonding materials, seals, etc.

This method establishes three test procedures: diurnal cycle effect, fogging, or rapid temperature change.

DYCOMETAL’s CCK-T climatic chambers are designed to accurately reproduce the most demanding environmental conditions in compliance with the requirements of MIL-STD-810H, method 524.1, guaranteeing the ability to simulate thermal cycles and environmental conditions according to the most rigorous military standards. This allows the behaviour and resistance of equipment to be verified in the face of extreme temperature variations, ensuring its performance and durability in any operating environment.

Which option should I choose: air or water condensation/cooling?

 Climate chambers need to be cooled in order to perform effective heat exchange and cool the working volume. To perform this exchange, they have a condenser, which can be air-cooled or water-cooled, each with its own advantages and disadvantages. As we have seen above, air condensation is usually the standard for chambers with lower requirements. However, when high temperature gradients are required or the cooling unit’s performance is greater, it is advisable to use a water-cooled condenser, as this will help to reduce the heat and noise generated by the cooling unit. Furthermore, although air condensation is cheaper to install, it is less efficient, with higher operating costs due to its lower thermal efficiency, higher energy consumption and greater noise.

To do this, you need an external cooling unit (chiller) or a water cooling tower that supplies a continuous flow of clean, temperate water (between 5 and 30 ºC) to remove the heat generated during the cooling of the chamber, allowing you to handle more thermal load than air cooling. To avoid water consumption, the best option is a water recirculation unit, a closed circuit that continuously removes water. Another advantage of water-cooled units is that they are not as affected by the external conditions where the equipment is installed and generate less noise.
The disadvantage is that these types of systems require a more complex installation (pipes, pumps, etc.) and an additional investment for the external water cooling system.

Consult our DYCOMETAL technical department for advice on the equipment that best suits your needs.

How does an air-cooled/condensed climate chamber work?

Test chambers remove or add heat from the product to the air, which increases or decreases the temperature in the chamber. The absorbed heat is circulated through the cooling system to the condenser, where it must be expelled. There are two cooling alternatives: air or water.

Standard climatic chambers or those with lower requirements are usually air-cooled, expelling heat directly into the room where they are located, which generates heat within the room itself that must be taken into account.
If the chamber is to be installed in a closed, unconditioned area, it is advisable to contact the manufacturer, as air-cooled chambers do not work reliably if the ambient temperature of the room where they are installed regularly exceeds +28 ºC or +32 ºC.

Another point to consider is dirt. The condenser constantly moves air flows and most chambers have the condenser located near the floor, which allows it to become easily dirty and clogged, increasing the working pressure of the equipment and therefore activating the overpressure safety devices. For greater chamber effectiveness, the condenser must be clean and free of obstructions so that air can circulate properly. Regular cleaning of the condenser will improve the chamber’s performance.

If the chamber is to be located in a dirty environment or where the atmosphere cannot be contaminated by noise, then the solution is to use a remote air cooling system (air condenser), removing the condenser from the chamber and placing it at a distance, usually outside, freeing the room from the heat and noise generated by the system. However, environmental conditions must be taken into account to ensure that the condenser can function properly under the environmental conditions of the country.

Climatic chamber for curing cementitious materials, CM-0/1200 ICH

 In compressive strength testing of cementitious materials, the preliminary curing of test specimens is an essential step to ensure the reliability of the results.

This curing process is carried out in climatic chambers under controlled conditions: 20 °C temperature and 95% relative humidity, for a minimum duration of 16 hours and a maximum of 3 days before testing.

During this period, it is crucial to frequently check that the surface of the specimens remains adequately moist, preventing any drying that could affect their mechanical performance.

The CM-0/1200ICH climatic chamber is a compact model with a large storage capacity. Its vertical design with a large interior height allows for the placement of samples of various sizes. Its stainless steel construction, both inside and out, ensures the robustness of the equipment for this type of high-humidity testing. All of this is controlled by a simple control system with associated recording software.

What temperature gradient should I select for my climate chamber?

Among the characteristics of climate or thermal test chambers, there is a variable that indicates the maximum speed that the chamber can reach for both heating and cooling. In order to define this gradient, the test standards to be applied normally indicate the recommended or maximum gradients for performing the tests.

We must not make the mistake of thinking that a higher gradient is better for reducing test times, as these increases can generate greater thermal stresses in the samples and can cause thermal stress within the sample. Many standards establish a maximum gradient to avoid this effect on the samples. Read the test standards carefully in order to select the most appropriate temperature gradient.

Please note that the gradients provided by chamber manufacturers are based on the IEC 60068-3-5 standard, the average temperature rate within the chamber without load and measured between 10% of the positive and negative temperatures of the chamber’s total temperature range. That is, for a climatic chamber from -40°C to +180°C, the temperature gradient according to IEC 60068-3-5 will be between -22°C and +158°C. This information is used to standardise gradient values, but this value is not always useful for selecting the most suitable chamber. The gradient will be reduced depending on the mass to be tested, the type of material, the sample’s heat dissipation capacity, etc. You must provide as much information as possible to ensure that the climatic chamber will meet your needs and those of the sample you wish to test.

Always consult DYCOMETAL’s technical sales department to select the equipment that best suits your needs.

WHAT HUMIDITY RANGE IS BEST FOR MY CLIMATIC CHAMBER?

Climatic chambers can control either the temperature or the humidity within them. This is a point that is sometimes difficult to understand, because the relative humidity (RH) percentage will depend on the existing temperature. The higher the temperature, the more moisture the air can hold.

Relative humidity is the ratio of the amount of moisture in the air to the amount it can hold. Changing the temperature changes the relative humidity, which makes temperature control very important, since stable temperatures ensure a stable humidity level.

The normal humidity range for test chambers is usually between 10% and 98% RH, ranging from 10°C to 90°C and limited by the dew point. Test chambers use the dew point to establish the relative humidity limit.

The best way to understand this theory is to look at the temperature vs. relative humidity diagram, which indicates the manufacturer’s humidity limits. It is important to work within these limits to prevent damage to the cooling system.

To achieve lower humidity levels, the chamber is usually equipped with an air-drying system to allow the coil to drop below freezing.

Climate testing regulations have well-defined temperature and humidity ranges. Please indicate the regulations you wish to follow so that DYCOMETAL can offer you the most comprehensive equipment in the humidity ranges you need to perform your tests. Since humidity depends on temperature, indicate the temperature points and the humidity at those points you wish to define so that we can properly define the humidification systems.

WHAT NEGATIVE TEMPERATURE RANGE DO I SELECT FOR MY CLIMATIC CHAMBER?

Climatic chambers can control both positive and negative temperatures. For positive temperature control, the chambers use electric heating elements, but for negative temperatures, there are different cooling options. Most climatic chambers use a mechanical system based on refrigerant gas compressors to perform the cooling.

There are several negative temperature ranges, but the standard used and the type of material or sample being tested will determine the negative range. The following must be taken into account: the negative temperature range indicated in the standard, energy dissipation, mass, and type of material, in order to calculate the cold group and determine whether it is the most appropriate. For example, if you want to lower the test temperature to -40°C with a large mass and high dissipation, a single-compressor chamber will not be sufficient, and you will need to select a two-compressor system with a larger negative temperature range.

There are several alternatives for lower temperature ranges, based on mechanical cooling or an expandable refrigerant.

• Ambient +10°C. This lower limit is common for non-cooled chambers. Since the fan generates its own heat, temperatures close to ambient cannot be guaranteed. If a temperature close to ambient is desired, a cooling system will be necessary.

• -25°C. This is a considerably lower range that can be achieved by refrigerants commonly used in refrigerators or air conditioners, using a refrigerant gas.

• -40°C. This type of cooling system is commonly called single-stage, as there is only one compressor in the cooling system.

• -70°C. Systems called cascade or dual-stage. The high stage will be used to cool the low stage, allowing the temperature limits to be lowered. The high stage will ensure no overpressure or overheating.

• -86°C. To achieve this cooling, a triple cascade cooling system is used. This is rare in climatic chambers, however, it is common for ultra-low temperature freezers.

• -170°C. Chambers that reach these limits use liquid nitrogen for cooling. Nitrogen is an inexpensive method for cooling a chamber; however, prolonged use can be expensive. It is typically used for tests requiring gradients close to 30°C/min with a small volume.
