CUSTOM MILITARY LIQUID CHILLER

Military Liquid chiller:

Here’s another custom military application by TECA.

Military grade liquid chiller

 

The United State Navy needed a liquid chiller to circulate coolant and also meet strict military requirements. TECA developed a custom thermoelectric liquid chiller using MIL rated components. This is a liquid chiller for circulating chilled coolant as part of a tracking system on a NAVY ship.

Note that the chilled liquid circuit is effectively “sandwiched“ between two heat sinks with rugged Mil 901 fans. Wiring and electrics are housed in a NEMA-4X/Harsh Environment enclosure with an O-ring gasket seal. This unit is rated for shipboard use in salt-spray, shock and vibration.

LIQUID CHILLER WITH 200′ HOSE

Liquid Chiller with 200′ Hose:

Liquid chiller with 200' hose

A customer wanted a TLC-1400 thermoelectric liquid chiller (Peltier chiller) to maintain a 400 watt load under normal conditions except for one thing, the hose needed to be over 200’ long. Would it pump? How much of an effect would it have on the cooling capacity? We could have run the numbers and come up with an estimate.

It was really easier to just hook up some hose and a constant load plate, roll it into the environmental chamber and see what it did. It did more than it was supposed to. The customers safely bought it knowing it would do what he needed.

CHILLING PROCESS INK

Here’s the way they’re all supposed to work:
September: Initial contact: Need help sizing unit that can maintain a liquid temperature between 25 °C – 35 °C in ambient conditions of 15 °C – 40° C. I need a unit for testing ASAP. In conjunction with sizing a chiller, I am also trying to size a heat exchanger. I need chiller flow rate and output temperature. Please call to discuss details.
