Rugged Liquid Chiller Unit

LCU-R 00002

This system was a design based off the previous Liquid Chiller Unit, but enhanced to improve the coolant flow rate, pressure capacity, and the overall system performance. This chiller provides over 350 W of cooling  and can operate over a broad range of ambient conditions (-35°C to 50°C).

  • Provides 200 W heating and >350 W cooling to a circulating coolant
  • Operates over a broad range of ambient conditions
  • Provides chilled or warmed coolant directly to customer cold plate with tight temperature tolerance (+/- 0.5°C)
  • Weight: 15 lbs, Size: 8 x 5.5 x 13 in.

System Description

Aspen developed a rugged liquid chiller unit for several customers who required a compact, lightweight liquid chiller which can operate in extreme environments and provided critical cooling and heating to their components as required. The system maintains a constant coolant temperature which is regulated to +/- 0.5°C. The system has a built-in pump and reservoir to circulate the coolant, which allows system to function without the use of a fill kit. The liquid chiller unit also has a communication port which allows the user to monitor the system performance and choose the operating temperature.

The compact design gives the user flexibility to design this chiller into their system or have is reside as a separate unit. Also, the cold plate, which ultimately removes heat from the payload, can exist remotely from the chiller and can be designed as appropriate to meet the customer’s requirements.

The chiller has been designed to meet the requirements of mobile applications where it may be subjected to shock, vibration, and a variety of environmental conditions.
