// For plant cultivation : RFI 2×400 water cooler //
Managing the right temperature in a climate chamber is essential for good plant cultivation.
Managing the temperature in a climate chamber for plant cultivation is essential to ensure their proper development and plant growing.
Each plant species has an optimal temperature range within which its biological processes—such as photosynthesis and respiration—function efficiently.
A temperature that is too low can slow germination, growth, and flowering, while a temperature that is too high risks causing heat stress and irreversible damage. Precise control also makes it possible to replicate natural seasonal conditions, which is essential for certain sensitive species.
This helps improve the quality and consistency of harvests by limiting unexpected variations.
Furthermore, thermal stability reduces the risk of diseases linked to unsuitable conditions. Regulating temperature also optimizes water and nutrient use, as plant needs change depending on the ambient temperature.
Proper temperature management also makes scientific experimentation more reliable and reproducible.
To address all these issues, we are supporting STRADER. This company, which specializes in climate chambers and phytotrons, designs and manufactures equipment for plant professionals (researchers, academics, laboratories, biotechnology professionals, etc.).
Our engineers designed a rather unusual chiller for their needs: equipped with two refrigeration circuits, this RFI produces 2 x 28 kW of cooling power for -2°C glycol water and 35°C ambient air. (Technical details below, with a photo of the final acceptance test at our premises.)
Thank you to the STRADER teams for this request: for plant cultivation or for any purpose, this type of “custom” project is always an opportunity for us to engage our support, engineering and manufacturing process with rigor and agility.
Some technical details about this RFI 2×400 chiller
- 2 separate refrigeration circuits operating on R513A, each with:
- 2 PANASONIC Scroll compressors mounted in tandem
- 1 brazed plate evaporator protected by a flow switch
- 1 micro-channel air-cooled condenser with 2 AC fans
- Condensing pressure regulation via pressure switches
- 1 thermostatic expansion valve
- 1 set of HP/LP pressure switches
- 1 common hydraulic circuit (in “tankless” configuration)
- 2 CM5-5 centrifugal pumps mounted in tandem, with a check valve and a set of upstream/downstream isolation valves
- 1 Y-filter with upstream/downstream isolation valves
- 2 solenoid valves for circuit selection
- 1 integrated electrical cabinet
- 1 front-mounted main disconnect switch
- ELIWELL FREE Advance PLC for pump management, Compressors, fault management, MODBUS TCP/IP communication, and a “Boost” mode (simultaneous operation of 2 pumps and up to 4 compressors)
- 2 separate power inputs, 63 A each.
