When is it Appropriate to Use a Compressed Air Supply?
STANMECH typically recommends that Leister’s LHS air heaters be supplied with air by a blower. This is because a blower-based process heat system, when correctly sized and installed, will be far more energy efficient than an equivalent compressed air system. The associated cost-savings increase with the power rating of the heater—larger heaters require larger volumetric air flows resulting in more savings.
However, when broken down to its basics, LHS air heaters simply require a consistent supply of air flow regardless of its source. As long as the system is capable of providing an uninterrupted supply of air that meets the minimum flow requirements for the heater, the LHS air heaters can be operated safely using compressed air.
The top 4 reasons for using compressed air instead of a blower are:
Best Practices for Operating a System with Compressed Air
Before operating a Leister LHS air heater with compressed air, there are two critical system details which must be verified.
Once the above questions have been answered and any issues addressed, the heater can be installed into the system. There are Leister adapters available to make an easy compressed air connection to the LHS air heaters. However, non-Leister fittings/adapters are acceptable if they are rated appropriately for the pressure and do not restrict the volumetric air flow below safe levels.
