Features Designed for any Application
Industry-leading single-stage efficiencies, standard features, and a variety of options - providing energy efficient solutions to accommodate your building requirements. The EP Model, water-to-air heat pump offers high efficiency, value added features and a single stage compressor (scroll type 1 1/2 - 6 ton size). An optional ECM constant airflow fan motor can give you the flexibility, performance and quiet operation needed to meet the expectations of your clients.
ECM Constant Airflow Fan Motor
The high efficiency Electrically Commutated Motor (ECM), available in 1/3hp to 1hp, provides constant airflow in a wide static pressure range up to 1 in.w.g. Optional in all unit sizes except 1/2 through 1 ton, this motor is a great choice in high filtration applications. The motor has a soft start/stop feature, keeping noise to a minimum. Passive dehumidification can be achieved with the constant airflow ECM by reducing nominal airflow by 15%. This control feature lowers air coil temperature and prevents over-cooling of the space when in dehumidification mode. The constant airflow ECM requires a neutral wire in a 460V application.
Blower and Motor
PSC blower motors are standard on unit sizes 1/2 through 1 ton. Multiple speed constant torque ECM motors are standard on units sizes 1 1/2 through 6 tons, allowing the user to select the correct speed to deliver the specified airflow and the design system static pressure.
MERV-8 and MERV-13 Filters
The optional 2" MERV-8 or -13 filter is most advantageous for premium air filtration on commercial HVAC projects. High efficiency filtration is a cost-effective way of upgrading air quality while maintaining low pressure drop and sustaining long service life. These filters effectively remove up to 98% of airborne matter, such as fine particulates, bacteria, smoke, gases and allergens including dust mites, pollen, mold spores, dust and smog. MERV-8 and MERV-13 rated filters are a minimum requirement for EQ credits 3.1 and 5 on LEED® projects.
The optional factory mounted DDC Controller is preprogrammed and installed on the unit with the Unit Protection Module (UPM) to be job site ready. With a factory-supplied DDC wall sensor, the unit will operate in a 100% stand-alone control mode or connect to a Building Automation System (BAS) using open protocols BACnet™, Modbus, N2 or LonWorks® (with an optional Lon card).
DDC Room and Zone Sensors (optional)
To complement the controller, Bosch Thermotechnology Corp. offers a line of intelligent FHP space sensors, which provide precision measurement and communication capabilities in an attractive low profile enclosure.
