Equipment operating in remote locations, often needs to run unattended for long periods. If that equipment is working in hazardous gas or dust environments, they need dependable components that are durable and that require little maintenance. All filter media needs regular maintenance and since they need to be replaced periodically, replacements must be purchased, transported to the remote area and when they are used up, they must be disposed of. When environments in which they work contain hazardous gases or dusts, their motors and controls must be suitable for the explosive gases and dusts. Hazardous-duty Air-Cleaning BlowersTM (ACBs) offer the advantage that they do not need filter media or its maintenance so that they need a minimum of attention. APS’ hazardous-duty refrigerant compressors are not only durable themselves, (most are heavy-duty scrolls) but they also eliminate the need for open compressors with their belts that loosen, vibrate and wear out and their seals that often leak. Hence, they too are especially suitable for remote, unattended applications.
Easy Installation, Maintenance and Repairs:
Andover Protection Systems makes all of their compressors with a threaded plug on the 3 1 /2” (8.9 cm) ID enclosure. This makes wiring, and even rewiring, easy because a technician can fit their hand inside to work on the wiring.
No other compressors are tested and expressly recognized by Underwriters Laboratories (UL) as safe for use in either Division/Zone 1 or Division/Zone 2 locations in any class or group.
APS does not change the operation or performance of the compressors, just makes them safer.
When you assemble a complete product, APS’s proven designs and UL’s recognitions assure that the compressor is safe for the indicated environments and therefore that part of the unit will not have to be tested independently to verify its safety, thereby reducing the costs of UL listing of your products.
Protect electrical connections in corrosive, wet, and other harsh environments
APS protects all its compressors with resistant coatings to assure long life in corrosive environments.
Durability
APS offers scroll and reciprocating compressors with POE, mineral and other types of oils in capacities from 1/20 Horsepower to 30 HP and for low, medium and high-temperature applications.
Protects electrical connections in corrosive, wet, and other harsh environments
APS protects all its compressors with resistant coatings to assure long life in corrosive environments.
Reminder about “Explosion-Proofing”
Even when APS adapts its units for flammable and explosive environments, they retain all their other harsh-duty advantages and durability. Therefore, they afford a far better return on investment than do residential or commercial units modified for hazardous locations. In addition, APS makes a special priority the development and production of robust Division/Zone 1 and Division/Zone 2 compressors.
