Climate chambers

A climate chamber is a storage unit or walk-in safe where substances are heated or cooled, or stored at a constant temperature. Climate chambers are built by KOK Environmental Storage Systems for indoor or outdoor placement and in any desired size. The temperature range for which KOK Environmental Storage Systems designs climate chambers is from -18 °C to +80 °C.

Refrigeration and cooling systems are always electrical systems and are composed of a compressor (outside) and an evaporator (inside).

Heating can also be an electrical installation, but can also be carried out using steam or thermal oil. Connection to a central heating system or heat pump is also possible.

If a climate chamber must also comply with the PGS 15 guideline, the cooling and heating installations can be designed to be ATEX (Ex) compliant.

For temperatures between 18 °C and 25 °C, an “inverter” air conditioner is a suitable high-efficiency solution. The cooling and heating capacity of an inverter is 3 to 4 times higher than its power consumption.

If the temperature needs to stay below 18 °C, a cooling system is required. The necessary capacity is determined based on the functional requirements. Temperature control and monitoring can be based on local control or connected to a “factory control system”.

Steam heating is an efficient method of heating. Because steam at a pressure of 5.5 bar has a temperature of approximately 155°C, it can be used via a heat exchanger to achieve a high temperature in the heating chamber.

Large spaces can be heated with a ducted air heater combined with a box fan and an air distribution system. In this way, a constant and stable temperature can be achieved in all corners and at all heights of the heating chamber.

A finned tube heater is suitable for frost protection or for heating up to a maximum of 30°C. These heaters are available with a range of outputs between 250 W and 3,000 W and can be supplied in ATEX versions.

To achieve a temperature of 30°C to 80°C, an electric duct heater is used. The power is determined by the required energy and the time duration within which the heating must take place. Temperature control and monitoring can be based on local control or connected to a “factory control system”.

Climate chambers with KOK Milieuopslagsystemen

KOK Environmental Storage Systems builds climate chambers for substances and products that need to be stored at a controlled temperature. Whether it involves cooling, heating, frost protection or constant-temperature storage, the technical design is tailored to the application. In doing so, KOK considers not only climate control, but also safety, regulations and daily use.

What is a climate chamber?

An environmental chamber is a room in which products are cooled, heated or stored at a constant temperature. At KOK Milieuopslagsystemen, an environmental chamber is often designed as a racking container or as a walk-in safety store. This allows substances to be stored safely under the correct temperature conditions.

What is the function of a climate chamber?

The function of a climate chamber is to create a stable and controllable storage environment. This is important for products that are sensitive to heat, cold or temperature fluctuations. A climate chamber helps to store substances at the correct temperature and to carry out processes such as heating, cooling or frost-free storage in a controlled manner.

What is a environmental test chamber used for?

A climate chamber is used for substances or products that need to be stored under controlled temperature. Think of chemical products, raw materials, liquids, packaged hazardous substances, production components or temperature-sensitive materials. The application determines whether cooling, heating, ventilation, insulation or an ATEX design is required.

How much does a climate chamber cost?

The costs of a climate chamber depend on the dimensions, the desired temperature range, any PGS 15 requirements and additional options such as ATEX components, temperature monitoring or redundant execution. Because climate chambers are custom-built, there is no fixed standard price. For a good price indication, the desired capacity, the stored substances, the location of the climate chamber and the temperature requirements are needed.

Is a climatic chamber the same as a cold room?

No, not always. A cold store is primarily designed to keep products cold. A climate chamber can be used for a wider range of purposes: for cooling, heating, frost protection or storage at a constant temperature. Depending on the application, a climate chamber can therefore be designed as a cold store, a heated chamber or a combined temperature-controlled storage area.

Can a climate chamber be heated?

Yes, a climate chamber can be heated. This can be achieved, for example, using electric heating, steam, thermal oil, a central heating system or a heat pump. Which heating solution is most suitable depends on the desired temperature, the size of the room, energy consumption and the materials being stored.

When do I need an environmental test chamber?

You need an environmental chamber when substances or products only remain safe or of good quality within a certain temperature range, or if a specific temperature is required for the processing of those substances. This can involve products that must not freeze, need to be kept refrigerated, or must be stored at a constant temperature. Temperature control can also be important for safety and product quality when dealing with hazardous substances.

What temperature range is possible in a environmental test chamber?

KOK Milieuopslagsystemen designs climate chambers for a wide range of temperatures, from freezing and cooling applications to heat chambers. The correct execution depends on the desired storage temperature, the outside temperature, the insulation, the product volume and the speed at which products need to be cooled or warmed up.

Can a climate chamber be cooled?

Yes, a climatic chamber can be fitted with a refrigeration system. This is necessary when products need to be kept below a certain temperature. At lower temperatures, the required cooling capacity is determined based on the desired temperature, the volume of the room, the insulation value and the operating conditions.

When is air conditioning suitable for a climate chamber?

Air conditioning is particularly suitable when the desired temperature is within a moderate range, for example around room temperature. An inverter air conditioner can efficiently cool and heat within a limited temperature range. When the temperature needs to remain structurally lower, a true refrigeration system is required.

What is a heat chamber?

A heating chamber is a climate chamber designed to heat products in a controlled manner or to keep them warm. This may be necessary to keep liquids in a workable state, to prevent crystallisation, or to bring products up to the correct process temperature. The heating method is tailored to the desired temperature and the heating time.

What is a cold room?

A cold store is a climate-controlled room in which products are stored under refrigerated conditions. This is important for substances or materials that are temperature-sensitive or whose quality deteriorates at excessively high temperatures. The refrigeration system is designed on the basis of the desired temperature, the size of the room, its intended use and the products to be stored.

Can a climatic chamber be used for hazardous substances?

Yes, a climate chamber can be designed for the storage of hazardous substances. In that case, one must look not only at temperature control, but also at fire safety, spill containment, ventilation, compartmentalisation, and any PGS 15 requirements. The design depends on the substances and quantities being stored.

Can a climate chamber comply with PGS 15?

Yes, when hazardous substances are stored, a environmental chamber can be designed in accordance with the requirements applicable to the situation. Factors such as fire resistance, spill containment, ventilation, distance requirements and safe installations play a role in this. KOK Milieuopslagsystemen tailors the environmental chamber to the substances, location and regulations.

When is an ATEX version required for a environmental test chamber?

An ATEX design may be necessary when there is a risk of an explosive atmosphere forming, for example due to flammable vapours. In that case, electrical components, cooling and heating installations and other equipment must be suitable for the relevant risk zone. Whether ATEX is required follows from the risk assessment and evaluation (RI&E) of the facility where the environmental test chamber is placed.

Can the temperature in a climatic chamber be monitored?

Yes, temperature control and monitoring are possible. This can be controlled locally or linked to a central system, such as a factory control system. This enables the temperature to be monitored and intervention to take place when it falls outside the set values.

Can a climate chamber be placed indoors?

Yes, climate chambers can be installed indoors. Factors to be taken into account include available space, ventilation, accessibility, power supply, heat or condensation extraction, and the safety requirements for the substances being stored. The design is tailored to the specific location.

Can a climate chamber be installed outdoors?

Yes, a climate chamber can also be installed outdoors. When installing outdoors, insulation, weather conditions, the ground surface, accessibility, the power supply and safety are particularly important. The installation must be suitable for the environment in which it is to be used.

Can a climate chamber be custom-made?

Yes, KOK Milieuopslagsystemen builds bespoke environmental chambers. The dimensions, layout, insulation, cooling or heating system, product containment, ventilation, fire resistance and any ATEX specification are tailored to the application. This creates an environmental chamber that suits the substances, working method and location.

Can KOK Milieuopslagsystemen advise on environmental chambers?

Yes, KOK Environmental Storage Systems collaborates on climate chambers for the controlled storage of substances. This involves looking at temperature control, safety, regulations, energy consumption and practical use. This results in a solution that matches the products, the location and the daily process.
