Hi-Pres® Marine Self-Contained A/C Unit Type NovPac-R/G TYPE NOVPAC-R Product description COMPRESSOR NovPac-R/G models use hermetic reciprocating compressors. The compressors are tted with heating elements and an internal suction accumulator (for azeotropic refrigerant) to ensure long life operation. CONDENSER A cleanable shell-and-tube condenser with 90/10 Cu/Ni tubes is used for sea water, and a cast iron shell and Cu tube condenser for freshwater. Automatic seawater valves and air cooled condenser are optional. FEATURES Packaged air conditioners NovPac-R/G specially designed for use in marine and offshore installations. These units can be used for all kinds of small capacity air conditioning requirements. Cooling coil for direct expansion High-efciency centrifugal fan Hermetic reciprocating compressor with low sound generation Cu/Ni shell and tube condenser for seawater, a cast iron shell and Cu tube condenser for freshwater, a Cu/Al air cooled condenser for air Control panel with motor protection by thermal overload relay, temperature control and compressor control Thermostatic temperature control Standard refrigerant R404A or R407C, other refrigerants on request Standard range of units for 3x400V/50Hz or 3x440V/60Hz for freshwater, seawater or air cooled condenser. Air lter (EU-2),EU-4 is optional NovPac-R Contents: Specially designed for ECR etc, with capacities 6, 10, 14, 17, 20, 27 kW NovPac-G Contents: Specially designed for Galley, with capacities 10, 17, 27, 35 kW CASING Cold-rolled steel sheet casing built on a rigid galvanized steel frame. The casing is thermally insulated to prevent condensation and surface treatment by plastic spraying to resist corrosion. Plenum with adjustable grill and fresh air intake is optional. HI-PRES MARINE & OFFSHORE AIR COOLER Cu/Cu coil for NovPac-G, Cu/Al coil for NovPac-R. The evaporation process is secured by a thermostatic expansion valve. A washable at lter is placed in front of the air coil. The unit has a drip tray with extra depth to take pitch and roll into considerations, material of drip tray is plastic spraying treated Cold-rolled steel sheet, and stainless steel sheet is optional. FAN For optimum sound reduction a dual fan program is applied: fans with low static pressure for plenum to ensure a low noise level and high static pressure for duct connection, centrifugal fan with motor V-belt coupled. UNIT CONTROLS A digital temperature controller, with LED and sensors placed in the air ow, ensures the correct temperature. The LED is located on the small panel in front of the unit as well as switch knob for choosing operation mode such as, cool, heat, ventilation or remote on/off of optional equipment. The electric panel includes automatic circuit breakers. The compressor safety equipment includes HP/LP switches, lter/drier and liquid refrigerant sight glasses, and ttings to plug in pressure gauges. OPTIONAL EQUIPMENTS Plenum Damper for fresh air intake and/or counter anges Return air intake for a duct connection Flexible connections and counter anges for air intake and outlet Stainless steel casing Cu/Cu cooling coil Electric heating coil Automatic seawater valve Pressure gauges
