VA 40 Series

Vertical Air Conditioners for Severe Duty and Hazardous Locations

VA 40 Series Air Conditioners are engineered for severe duty industrial and offshore service. Explosion proof models meet the requirements for use in hazardous locations under the National Electrical Code (NEC) Class I, Groups B, C and D or Class II, Groups E, F, and G in Divisions 1 and 2.

These rugged air conditioners are built for maximum performance, reliability and safety. Cabinets are 14 gague galvaneal steel with 16 ga access panels. A two-part epoxy primer and attractive textured urethane topcoat provide excellent corrosion protection. Drain pans are Heliarc welded stainless steel. All mechanical and electrical components are selected for durability and minimum need for maintenance in demanding industrial environments. Switches and annunciator lights are sealed and industrial grade. Circulating air blowers are belt driven with adjustable speed pulleys. Bearings are permanently lubricated. Severe service motors are totally enclosed (TEFC) with a 1.15 service factor.

When simultaneous building pressurization (NFPA 496) is required, PB 24** Combined Air Conditioning / Pressurization units must be specified. Other options and accessories include explosion proof models, stainless steel cabinets, steam or electric heaters, SaveCoil 101** baked phenoxy coil coatings, and water-cooled condensers.
