Aermec is introducing large water and air cooled heat pumps to the US industry. Ideal for two pipe fan coil systems, a heat pump can supply cold water in the summer and hot water in the winter. For cold climates, heating should be supplemented with hot water boilers.
Aermec chillers are designed to recover heat for hot water heating, domestic hot water, or any process. When equipped with heat recovery, a third heat exchanger is supplied. This allows only the amount of heat required to be recovered into the system. Excess heat that is not required is rejected via the condenser coils. On a water cooled system, this has the added benefit of separating the condenser water system from the heating system. No 3rd party heat exchanger required.
SIMULTANEOUS HEATING AND COOLING
Aermec has introduced the next generation of heat recovery, simultaneous heating and cooling. Aermec's electric chillers can meet a heating setpoint and a cooling setpoint simultaneously regardless of load. Heating is recovered when the system has a higher demand for cooling; and cooling is recovered when the system has a higher demand for heating. This 4 pipe system is an ideal alternative to the common VRF system.
Aermec air cooled chillers have a factory option for free cooling. Free cooling introduces a set of water coils to the condensers of the chillers. When the ambient air drops below the return water temperature, free cooling is activated. The chilled water runs through the free cooling coils and is cooled similar to a dry cooler. Any additional cooling required is accomplished through regular mechanical means. Aermec's free cooling solution is a factory option and is completely tested and certified. It is not a custom or 3rd party solution.
The Aermec NYB chiller was designed to meet the requirements for buildings seeking exemption from the New York City stationary operating engineer law. Each 30 ton module utilizes two fully independent refrigeration circuits with compressor ratings less than 15 horsepower each, as required for the exemption. The NYB is the only chiller with integrated free cooling coils that is AHRI certified to meet ASHRAE 90.1-2010 minimum efficiency levels. The microchannel condensers allow a 40% lower charge of zero ODP R410A refrigerant. A free source of hot water is available using the desuperheater option.
INDOOR DUCTED AIR COOLED
Aermec's indoor ducted air cooled chiller and heat pump offer plenum style condenser fans for 12 sizes from 15-75 tons. Ideal for tenant cooling such as floor by floor designs and/or backup cooling. Coupled with a fan coils, this system maximizes floor to ceiling heights by reducing ductwork. Chillers are also available with heat recovery and pump packages.
Aermec's standard solutions are oftentimes the quietest available in the US market. In extreme circumstances, even quieter units may be required. Aermec's low noise options offer whisper quiet operation that help ensure that NYC sound codes are abided by.
All Aermec chillers are constructed in their ISO 9001 certified state-of-the-art manufacturing plant. The manufacturing process is completely automated which minimizes quality and consistency issues that plague many other manufacturers. Aermec products are completely AHRI and Eurovent certified to meet specified performance levels.
Aermec's air cooled and water cooled chillers are available with unit mounted pump packages for low and high head applications. Pump packages come with pumps, expansion tanks and optional buffer tank.
