The Vertical High Static (VHS) Systems are intended to deliver refrigerated air to medium to high temperature spaces. You will find these evaporators powerful and can be situated as far up to twenty five feet distant from the climate controlled wine room. The cooled air is ducted back into the wine cellar, virtually eliminating any noise and of course the inconvenience associated with evaporators which have to be placed in the wine cellar, this can also free up storage space otherwise lost.

VHS evaporators are available in capacities from 1,800 to 20,000 BTUs every hour. To be used with an R134a refrigerant.

Available Options

• Copper or coated coils for coastal/special applications
• Secondary drain pan for elevated and sensitive installations
• Stainless steel cabinets for high corrosive environments
• Eco-friendly water-cooled condensing units available
• Industrial applications available

• Installation diagram shows the typical duct layout. Actual layout to be determined by installer.
• Duct work not to exceed 50′ total length.
• For short duct length mat install a fan speed to slow down fan speed.
• Keep line sets as short as possible.
• The system is controlled by a pump down control system. There is no control wiring between thermostat and condensing unit.
• Drain line must always flow downhill to drain or pump.
• Standard line sets should be 50′ or less. Extended runs may require larger line sizes and 3oz. oil must be added for every 10′ over 35′.
• The line connections at Fan Coil and Condensing Unit may not be the same as the required line sizes.
• Excessive number of turns will cause refrigerant flow problems. This could cause early compressor failure. Suction line accumulators are recommended. Required if working lower than the normal 55-65° operating range from wine cellar.
