Lync’s Aegis A is a powerful commercial CO2 heat pump water heater powered by R744, better known as refrigerant grade CO2. Aegis A produces hot water up to 185°F at air temperatures as low as -4°F with no need for supplemental heat. By simply absorbing and moving heat from the surrounding area instead of needing to generate heat, this heat pump is extremely efficient thus saving energy and lowering operating costs.
