Design Envelope 4392 Twin Pumps for Commercial Heating and Cooling
Applications
HVAC-system pumping; general purpose pumping; industrial/process pumping (water or glycol based)
Description
Pipe-mounted 2-pump unit with integrated intelligent controls for space-saving installation, superior energy performance, and duty/standby operation. Saves up to 75% in energy over comparable traditional constant speed or variable frequency operated pump installations.
Materials
Performance range
Up to 1,100 USgpm (69 L/s) flow; up to 100 ft head (30 m)
Temperature
250oF (121oC)
Power Range
1 hp to 7.5 hp (0.75 kW to 5.5 kW)
Size
2" to 5” (50 mm to 125 mm)
Lowest installed cost
Vertical in-line design eliminates the need for inertia bases, housekeeping pads, and flex connectors, and reduces piping requirements
2-pump casing for reduced footprint
Integrated intelligent controls eliminate procurement, installation (incl. wiring), calibration and upkeep of differential pressure sensors
Superior energy performance qualifies for significant cost recovery under utility and government rebate programs
Lowest operating cost
Integrated intelligent controls – combined with perfect component match-up and tuning – provide up to 75% in energy savings over traditional constant speed and variable frequency operated pumping installations
Advanced seal design eliminates the need for lubrication and seal adjustments
Shorter pipe runs reduce system friction
Lowest environmental cost
75% decrease in energy consumption reduces operational greenhouse gas emissions at equal ratio
Elimination of inertia bases, housekeeping pads, flex connectors and superfluous piping avoids all procurement related environmental impacts (material, energy, carbon)
Equipment downsizing mitigates environmental impacts associated with procuring unnecessarily large equipment
Integrated Twin design packs and ships more economically for less packaging waste compared to loose component shipping and assembly
Lowest project and operating risk
Integrated intelligent controls combined with perfect component matching and turning make commissioning fast and easy
Integrated controls reduce radio frequency interference and improve electromagnetic compatibility
Single source-responsibility for optimum design and field support
Twin design provides full redundancy in case of emergency or routine servicing
