Mechanical Specifications

Unit-mounted or remote-mounted starters for Europe (CE mark) will be star-delta, solid-state, across-the-line, primary reactor, and auto transformer only in a IP 20 enclosure.

A steel panel door with optional mechanical interlock disconnects the system when the door is opened (required for CE listing). The panel also contains three-phase current transformer for overload protection, and an oil pump starter with overloads. The starter is factory mounted and wired to the compressor motor and the control panel. The CVGF chiller/starter assembly is factory tested.

Optional remote mounted electromechanical starters are available.

Isolation Pads

Molded neoprene isolation pads are supplied with each chiller for placement under all support points. Spring isolators are optionally available.

Refrigerant and Oil Charge

A full charge of oil is supplied with each unit.The oil ships in the unit’s sump and the refrigerant ships directly to the jobsite from refrigerant suppliers.

Painting

All painted CVGF surfaces are coated with two coats of air-dry beige primer- finisher prior to shipment.

Insulation

The chiller can be ordered with or without factory applied insulation. Factory supplied insulation is applied to

all low temperature surfaces including the evaporator, water boxes and suction elbow. Insulation material is 19

mm(¾ in.) Armaflex II or equal (thermal conductivity = 0.04 W/m·°C; 0.3 Btu·in/h·ft²·°F). The oil sump is insulated with 9.5 mm (3/8 in.) and

13 mm (½ in.) insulation respectively.

Rigging

Evaporator and condenser tube sheets provide rigging support points. A rigging diagram is affixed to the chiller.

Quality

The La Crosse chiller manufacturing facility is ISO 9001.
