Inline, end-suction and VFD booster pumps with IE3/IE4 motors for commercial buildings, industrial zones and data centers — European standards, full submittal documentation for MEP design.
4 common issues in chiller plant and commercial HVAC operation — and how TKT's high-efficiency IE3/IE4 pumps address them at the root.
Legacy IE2 pumps consume approximately 25% of total HVAC energy. In high-rise buildings, the chiller pump system runs 24/7 without optimized loading — no VFD, no match to actual cooling load. The longer they run, the more energy they waste.
Pumps lacking inline isolation, improper anti-vibration mounts, and rigid piping transmit vibration into the building structure. Tenants on upper floors complain and property NPV decreases — especially in hotels and upscale condotels.
Fluctuating chilled water flow — upper floors under-cooled, lower floors over-cooled, chillers running at full capacity. Root causes: no VFD on pumps, no DPS sensors, improperly set balancing valves.
Data centers, hospitals, 24/7 manufacturing plants — a single chiller pump failure means loss of cooling, server downtime, vaccine spoilage, production line shutdown. Systems without hot-standby and condition monitoring carry significant risk.
From chiller primary loop, secondary loop, condenser loop to cooling tower and AHU blower — TKT supplies the complete range from a single source.
Vertical inline pump mounted directly on the main pipeline, no separate baseplate required — ideal for compact chiller plant rooms and multi-storey high-rises.
End-suction and multi-stage horizontal pumps for high-rise buildings, high-heat-load condenser loops — high head, stable efficiency, easy maintenance.
A set of 2–6 vertical multistage stainless steel pumps with VFD control — DOOCH MQ/XQP Series integrates VFD in each pump, soft start, maintains stable pressure, saving up to 50% energy compared to full-load operation.

Central chiller — produces chilled water for the entire building's air conditioning system.
Primary loop between chiller and buffer tank — constant flow rate, stable pressure.
Secondary loop distributing chilled water to AHU/FCU on each floor — variable flow rate according to load.
Cooling tower and condenser water loop — rejecting heat to the environment.
