The PIRANHA Series
HEATING & COOLING USING WASTEWATER
The PIRANHA Wastewater Heat Recovery & Cooling System is a specialized water-to-water heat pump that recovers energy directly from wastewater and uses this source energy to produce hot water.
Typically used for potable Domestic Hot Water (DHW) purposes, it can also be used for hydronic heating or alternate hot water demand purposes.
Why PIRANHA Series?
- Intelligently recover heat energy using wastewater to greatly reduce new energy consumption & CO2 emissions
- Reduce cooling costs
- Consistent year-round performance
- Compact, small footprint heat pump powerhouse
- Fully automated
- Increase COVID-19 readiness with building-wide testing
PIRANHA Series
Each PIRANHA unit contains an onboard electrical/control panel that provides full system automation, including operation of the wastewater supply pump, automated drain valve/wastewater discharge pump, and full system monitoring/trending of source and supply temperatures.
Heating
- The PIRANHA HC’s specially designed evaporator recovers and transfers energy directly from wastewater into a refrigeration circuit
- NSF-372 rated double-wall vented brazed plate heat exchanger (condenser) transfers the energy directly into potable water.
PIRANHA HC Series
The PIRANHA HC Series amplifies performance by adding the ability to provide simultaneous space cooling alongside domestic hot water production.
Cooling
- The PIRANHA HC’s specially designed evaporator recovers and transfers energy directly from wastewater into a refrigeration circuit
- A second, independent evaporator recovers energy from a hydronic space cooling loop and adds that energy to the refrigerant circuit, boosting performance.
- NSF-372 rated double-wall vented brazed plate heat exchanger (condenser) transfers the energy directly into potable water.
