Air-Cooled Heat Exchangers

Air-cooled heat exchangers must be sized to provide adequate cooling under the most severe conditions, which probably 

means providing for an ambient temperature of 40°C. Once the cooler is in place and working, precautions must be taken 

to prevent restriction of the cooling air flow to and from the cooler and recirculation of the cooling air.

Safety Valves

Safety valves are pressure relief valves and should be sized and purchased with a pressure setting to protect the weakest link 

in the system. Never change the pressure setting. Only the safety valve manufacturer or certified ASME valve repair shop 

is qualified to make a change.

Safety valves are to be placed ahead of any potential blockage point which includes, but is not limited to, shutoff valves, 

heat exchangers, pulsation dampeners, and discharge silencers. Ideally the safety valve should be threaded directly into the 

pressure point it is sensing, not connected with tubing or pipe, and pointed away from any chance bystander.

The safety valve shall prevent pressure in the weakest component from exceeding 110% of the maximum allowable working 

pressure during maximum flow conditions but must not be set higher than the maximum working pressure of the weakest 

link. Failure to properly size, set and install pressure relief valves can be fatal.

Pressure Vessels

Air receiver tanks and other pressure containing vessels, such as, but not limited to, pulsation bottles, heat exchangers, 

moisture separators and traps, shall be in accordance with ASME Boiler and Pressure Vessel Code, Section VIII, and/or 

Provincial Boiler Branch Requirements. Failure to adhere to these codes can be fatal. Most Governments keep track of all 

pressure vessels. Yours should be subject to an inspection by authorities.

Electrical

Before  installation,  the  electrical  supply  should  be  checked  for  adequate  wire  size  and  transformer  capacity.  During 

installation a suitably fused or circuit breaker disconnect switch and motor starter should be provided. Where a 3-phase 

motor is used to drive a compressor any unreasonable voltage unbalance between the legs must be reduced and any low 

voltage corrected to prevent excessive current draw. The installation, electric motor, wiring and all electrical controls must 

be in accordance with ANSI Cl National Electric Code, ANSI C2 National Electric Safety Code, State/Provincial and 

Local Codes. All electrical work should be performed by a qualified electrician. Failure to abide by the codes may result in 

physical harm and/or property damage.

Guards

All mechanical action or motion is hazardous in varying degrees and needs to be guarded. Guarding shall be in compliance 

with OSHA Safety and Health Standards 29 CFR 1910.219 in OSHA Manual 2206, Revised November 7, 1978 and any 

Provincial, State or Local Codes.

Guards, if supplied, must be fastened in place before starting the machine and never be removed before switching off and 

locking out the main power supply.

Manual Relief and Shutoff Valves

Install a manual relief valve to vent the compressor and the compressor discharge line to atmosphere. In those instances 

where the air receiver tank services a single compressor, such as a tank-mounted unit, the manual relief valve can be 

installed in the receiver. Where a manual shut-off valve (block valve) is used manual relief shall be installed upstream from 

the manual shut-off valve (block valve), and a safety relief valve installed upstream from the manual relief valve. These 

valves are to be designed and installed as to permit maintenance to be performed in a safe manner. Never substitute a check 

valve for a manual shut-off valve (block valve) if it is the purpose of the manual shut-off valve to isolate the compressor 

unit from a system for servicing.
