RSL
Over 100 Cable & Wireless DX AHU units (6-12 KW) have been converted to RS-44 at Bristol. Simple and straightforward procedure. Lower discharge pressure and discharge temperature produced significant operating benefits. Previous problems of trip out at high pressure with R407C avoided. Ran with no problems through hot summer with high ambient temperatures.

CARRIER SPLITS CONVERTED FROM R22 TO RS-44
Carrier Commercial converted twelve year old Carrier 25 to 30 ton split systems used for process cooling at Pratt and Whitney manufacturing facilities in Connecticut, USA.
The systems had reciprocating compressors manufactured by Carlyle. The conversion went smoothly according to Carrier Commercial’s service supervisor, who said:
“Not having to change the oil, valves or dealing with leaking seals was a big plus”.

* COMPATIBLE WITH MO, AB & POE OILS

40. RS-45 SUMMARY RSL * HIGHER MASS FLOW RATE THAN R22
* TXV SIMILAR TO R404A
* CHECK LIQUID LINES
* PIPE SIZING TABLES AVAILABLE
* USE RS-44 IN EXISTING SYSTEMS WITH CAPILLARY TUBE

41. RS-44 & RS-45 APPLICATIONS RSL
RS-44 IS SUITABLE FOR USE BOTH IN FIXED ORIFICE & SYSTEMS
WITH AN EXPANSION VALVE.
RS-44 WORKS WELL AS A REPLACEMENT FOR R22 AT MEDIUM &
HIGH TEMPERATURES.
RS-44 IS PARTICULARLY EFFECTIVE IN UNITARY AIR
CONDITIONING SYSTEMS
REPLACING R22 IN AN EXISTING SYSTEM WITH A CAPILLARY
TUBE OR FIXED ORIFICE, RS-44 IS THE PREFERRED PRODUCT
RS-44'S LOWER DISCHARGE PRESSURE PROVIDES CONSIDERABLE
OPERATING BENEFITS
RS-45 IS A CAPACITY MATCH FOR R22 ACROSS THE TEMPERATURE
RANGE

42. RS-44 & RS-45 APPLICATIONS RSL
RS-45 HAS BEEN FORMULATED FOR USE BY ORIGINAL EQUIPMENT MANUFACTURERS
AT LOWER TEMPERATURES, BELOW -25OC EVAP, RS-45 IS ESPECIALLY EFFECTIVE AS A R22 REPLACEMENT
RS-45 WITH ITS LOW GLIDE (AT 1.5oC CONSIDERABLY LOWER THAN R407C) PROVIDES A SIGNIFICANT BENEFIT IN SPECIFIC APPLICATIONS, EG FLOODED SYSTEMS.
BOTH RS-44 & RS-45 HAVE CONSIDERABLY LOWER DISCHARGE TEMPERATURES THAN R22
