»A New Technology:
Giving You More For Less!
Reciprocating compressors have, until now, carried the workload in applications requiring temperatures below -35°C. This was the technology of choice, mainly because cascading refrigeration systems was the only choice. Now...Envirotronics has crossed another technological threshold and is excited to offer screw-style compressor systems. These systems were developed specifically for use in applications of -40°C and below (down to -50°C). Originally designed for larger applications, this technology is now available in chambers requiring only a single 15 HP or larger compressor. With the development of this advanced screw-style refrigeration system, we are able to pass along these important benefits to you:
- Better
performance per HP
- Improved reliability
- Reduced costs
When your next purchase demands a low temperature range, down to -50°C, consider a screw compressor system, with its outstanding benefits.

»Fewer Moving Parts
By design and function, the
screw compressor has far fewer moving parts
than the reciprocating style. Engineered with
no valves and rolling element bearings, the
total number of parts is drastically reduced
as well. This reduction of parts is important
because it dramatically improves the
compressor's reliability rate, increases its
expected life-span and reduces the
maintenance factor.
»Higher Specific Output (BTUH/CFM)
Screw compressors outperform
other types of compressors. A 65 CFM
economized screw compressor will yield and
improved 134% specific output over that of a
99 CFM reciprocating compressor. It will also
occupy 37% less space and weigh 20% less.*
*Data based on actual tests
results of the Carlyle Compressor Division of
the Carrier Corporation.
»Less Vibration
Screw compressors are designed
to be perfectly balanced and have no
reciprocating motion present. This soft
compression brings the vibration levels down
to 1/130th of those found in comparable
reciprocating compressors.*
*Data based on laboratory
tests completed with a 30 HP Carlyle screw
compressor and a 30 HP reciprocating
compressor.
»Less Refrigerant Loss
Screw compressor technology
greatly reduces the risk of refrigerant loss
because of the decrease in vibration within
the entire system. Any structural breakdown
within a refrigeration unit may cause loss of
its valuable refrigerant. With the
accelerating costs of R-22, R-134a, and
R-507/404a, product loss becomes an important
operating factor.
