Hazardous and Severe Duty
Compressors
For air conditioning and
refrigeration
Andover Protection Systems
Manufactures an extensive line of
hermetic refrigeration compressors for explosive, corrosive, dusty, humid, and other
severe-duty industrial environments.
Our compressors are hermetically
sealed and have shielded electrical connections which are protected by heavy steel casings
that are virtually impenetrable to gases, dust and liquids. The enclosures also allow easy
access for wiring. The units come with a variety of anti-corrosion coatings, some of which
can withstand submersion in sea water.
Capacities range from
fractional to fifteen (15) horsepower. APS makes compressors for most voltages and for 50
and 60 hertz service. Most refrigerants can be used including CFCs, HCFCs and the newest
HFCs developed to protect the environment.
APS compressors are the first and only hermetic compressors in the world which have
Underwriters Laboratories’ (UL) specific recognition for locations classified as
hazardous.
Units made for Classes I, II and III, Groups B, C, D, E, F, G, Divisions 1 and 2
(and Zones 1 and 2).
PRINCIPAL APPLICATIONS
- Build and repair air conditioning and refrigeration
systems installed in explosive, dirty or corrosive environments.
- Extend the life of the compressors and electrical
connections in harsh environments with heavy-duty enclosures and a choice of standard and
special coatings. APS protects all its compressors with
DuPont's 25P® epoxy mastic
coating, but additional protection is available
- Eliminate the possibility of static electricity forming
on belts in hazardous environments and of the belts themselves corroding, wearing,
collecting dust, or slipping.
- Make construction and installation of air-conditioning
and refrigerating systems faster, easier and less expensive while increasing the
flexibility of the designs
- Replace open compressors, their motors and belts, and
thereby reduce noise and vibration.
- Eliminate the refrigerant leaks from the seals on open
compressors (APS hermetic compressors have no seals, only brazed connections).
- Make replacement of compressors easy, fast and simple
enough to be more economical than replacing the entire host unit, even when labor is
costly
- Build "explosion-proof" systems with
compressors which allow user permanent easy access to electrical connections
- Construct "explosion-proof" hermetic systems
using only UL-recognized components
- Repair and upgrade equipment despite restricted budgets
for new equipment
WHY USE APS COMPRESSORS?
- No other compressors are expressly recognized by
Underwriters Laboratories as safe for use in either Division 1 or Division 2 locations in
any class or group.
- When you assemble a complete product you can be
assured that the compressor is safe for the indicated environments and therefore that part
of the unit will not have to be tested to be sure it is safe, thereby reducing the costs
of UL listing of your products.
- The threaded plug on the 3 1 /2 " (8.9
cm) ID enclosure makes wiring, and even rewiring, easy.
- Unlike other compressor manufacturers,
APS protects
all its compressors with epoxy mastic coating—normally DuPont's 25P®—to
assure long life in corrosive environments.
- APS warranties its compressors for up to three
years, even when used in most dirty or corrosive applications.
