Description
The Penguin Chillers 1 HP High Efficiency Water Chiller is a general-purpose water chiller with 11,500 BTU/hr of cooling capacity. Penguin builds it for aquariums, hydroponics and process cooling, with the pump and plumbing chosen separately.
The high efficiency (HE) model uses a larger coil than the standard 1 HP for 11,500 BTU/hr on the same power draw. Choose a PVC shell with titanium coil, or a 316 stainless steel shell and coil.
Looking for a cold plunge chiller? For cold plunges, Penguin recommends its Cold Therapy Chiller, which has a built-in pump and is rated for outdoor use above freezing. This standard chiller is for indoor use only, has no pump and needs at least 250 GPH of measurable flow, so it is built for aquarium, hydroponic and process cooling setups. Not sure which fits? Ask us before you order.

Before you buy: what to know
Based on the manufacturer's specs, manuals and our research.
- This chiller has no pump. You need a separate pump and tubing giving at least 250 GPH of measured flow; Penguin recommends a Danner Mag Drive 5 to 18, rated under 10 PSI / 23 ft max head.
- Water must flow the whole time it runs, so unplug the chiller before you stop the pump. Condensation can form with cold water and humid air; place it where drips will not damage anything.
- This standard model is rated for indoor use only. For an outdoor plunge, Penguin recommends its Cold Therapy Chiller, which has a built-in pump and is rated outdoors above 32°F.
- The HE model uses a larger coil than the standard 1 HP, giving 11,500 BTU/hr on the same 7.2A, 830W draw. Penguin's lead time on this one is 3 to 5 business days.
- Penguin accepts returns requested within 21 days, unused and in original packaging, with a 20% restocking fee. Confirm your tub's fittings with us before ordering so a mismatch never comes to that.
