Has lower failure rates
A compressor that doesn’t operate doesn’t fail.
Bulldog uses the same compressors as any other manufacturer. However, our compressors will last longer. By eliminating all compressor operation during the heating hours we have reduced the run time hours and the quantity of start-stop commands, thereby extending the compressor life and reducing failures.
Result: Lower maintenance costs
Less down time
Fewer moving parts
The Bulldog provides a lifetime parts and labor warranty on reversing valves. It’s easy to do when we don’t have any.
The common point of failures with reversing WSHP is the reversing valve. Bulldog has completely eliminated this point of failure.
Result: Lower maintenance costs
Less down time
Fewer Water Loops
Since Bulldog operates with a warm water system in the heating mode, all of the HVAC loads (ie/ Bulldog Units, MUA, fin tube, in floor radiant heat, etc.) can be tied into one common loop, and provide more heat sharing (FreeHeat™).
Result: Lower energy costs
Simpler and less costly building piping loop = capital cost savings
Lower cost Make-Up Air System
Dry cooler capability
The Bulldog design allows for warmer loop temperature in the cooling mode.
Dry coolers may be used in lieu of evaporative type coolers due to the Bulldog condensers. The maximum inlet water temperature to allow cooling is 125⁰F at only 2gpm/ton.
Result: Lower capital costs
Lower maintenance costs
No risk of Legionnaire’s disease
Smaller Geothermal field
The Bulldog system integrates all the HVAC loads onto one common piping loop which maximizes the amount of heat absorbed from the Geo field and minimizes the amount of heat rejected to the Geo field.
Result: Smaller Geo field for cooling dominant buildings
Possibly fewer building water piping loops
Quieter
A compressor that doesn’t operate doesn’t make any noise.
The loudest mode of operation for a standard reversing WSHP is the heating mode since it operates at higher pressures. The Bulldog has eliminated the noisiest mode by operating as a simple Fan Coil in heating. Even with the compressor operating while in the cooling mode, the Bulldog unit is one of the quietest on the market.
