Joule Thomson Cryogenic Minicoolers

Our product range includes:

Fixed Orifice Joule Thomson Minicooler

Simple design to offer reliability at low cost when minimizing gas consumption is not critical

Benefits:

• Delivers high performance temperature stability
• Fast cool down times for short duration mission (typically less than 60 seconds)

Dual Flow Joule Thomson Minicooler

The Dual Flow Minicooler provides a variable control of gas flow with a high primary flow which cools the missile sensor to operating temperature in a rapid and precise time. The secondary flow maintains the sensor operating temperature while efficiently controlling the gas supply.

Benefits:

• Provides precise gas-flow management and speed control to deliver temperature stability of the detector
• Allows longer missions, typically up to 300 seconds
• Delivers significant weight savings through optimized gas supply

Demand Flow Joule Thomson Minicooler:

The Demand Flow Minicooler provides a continuous regulation of gas flow with a high primary flow which cools the missile sensor to operating temperature in a rapid and precise time. Once at temperature, the Minicooler controls the flow to match the heat load demand across a wide ambient temperature range. When compared with the Dual Flow Minicooler the Demand Flow Cooler increases precision and control to improve flight duration.

Benefits:

• Delivers high temperature stability for improved infra-red sensor stability through variable/throttling effect of gas flow
• Minimizes gas consumption over mission period improving mission duration capability
• Ideal for applications with either extended duty requirements or limited cooling gas availability
