Penguin Chillers Outdoor 1/2 HP High Efficiency Water Chiller

The Penguin Chillers Outdoor 1/2 HP High Efficiency Water Chiller is an outdoor-rated water chiller that puts a 5,750 BTU/hr cooling system inside a stainless steel exterior. It is built for exposed installations in any weather above freezing, so it can be set up outdoors and left there. It works as the chiller for a DIY cold plunge, a hydroponic reservoir, an aquarium system or an industrial process. A larger-than-standard titanium coil gets more cooling out of a 450 W draw on 110-120 V. Penguin Chillers builds it in Knoxville, Tennessee, and backs it with a 1-year warranty.

The front panel holds the controller display and both water connections, threaded 1 in. female NPT, a standard US pipe thread. Paired with an external pump, it works with water anywhere from 37°F to 100°F. The whole unit is 16.25 in. by 14.75 in. at the base, 12 in. tall and 49 lb.

High efficiency, built for outdoors

How it works

It pairs a proven 5,750 BTU/hr cooling platform with a stainless steel housing built for outdoor installations.

A larger titanium coil
The high efficiency (HE) coil is larger than the one in a standard 1/2 HP chiller, so the water gets more contact with the cold surface on every pass. More of the compressor's work reaches the water, with no extra power drawn to get it.
High efficiency
Stainless outdoor housing
A stainless steel shell and outdoor-rated construction let the chiller stay outside in all weather above freezing.
Above 32°F

Setup and placement

How to use it

Setup

Pump and plumbing

The chiller works with an external pump, plumbed into the inlet and outlet on the front panel, and the controller needs that water moving to read its temperature. Once water is moving, it plugs in through its 6 ft cord.

  • Danner Mag Drive 5.0 to 18 is the recommended pump
  • Any other pump needs a rating under 10 PSI / 23 ft max head
  • Keep water flowing whenever the chiller is plugged in
  • Unplug the chiller before stopping the water flow

Outdoors

Living outside

Stainless steel outside and built for exposed installations, it can be set up in the open and left there through the warm months.

  • Stainless steel exterior
  • Fan cycles on and off frequently in cool air
  • Condensation can form, depending on water temperature and humidity
