Penguin Chillers 1 HP High Efficiency (HE) Water Chiller

The Penguin Chillers 1 HP High Efficiency (HE) Water Chiller is engineered to provide exceptional cooling performance while maximizing energy efficiency. Delivering an impressive 11,500 BTU/hr cooling capacity, this high-efficiency model offers increased cooling performance over the standard 1 HP unit, making it an excellent choice for demanding applications such as reef aquariums, hydroponic systems, cold plunge and therapy tubs, laboratory equipment, and industrial process cooling.

Designed with reliability and durability in mind, the 1 HP HE Water Chiller is available with two heat exchanger configurations to suit a variety of applications. The PVC Shell with Titanium Coil is ideal for reef tanks and saltwater systems where corrosion resistance is critical, while the 316 Stainless Steel Shell & Coil is designed for higher-pressure freshwater and industrial applications.

Operating between 37°F and 100°F with water, the chiller provides precise temperature control while maintaining a quiet 59 dBA sound level. Its compact footprint, environmentally friendly R-32 refrigerant, and robust construction make it a dependable cooling solution for both commercial and residential installations.
