The QJB2.2/8-400/3-740 is the workhorse size for the cooling pond of a palm oil mill effluent plant. Two or more units installed along the pond create a slow circulation loop that spreads the hot 60 C POME across the surface, releases residual oil for skimming, and prevents the crust that blocks oxygen transfer before the anaerobic stage. The 400 mm propeller delivers 1250 N of thrust at only 2.2 kW, so a 2000 cubic metre pond can be turned over with two units running continuously.

Standard supply includes 415V / 50Hz / 3 phase for Malaysia and 380V / 50Hz / 3 phase for Thailand, with 220V single phase and 60Hz options on request. Motors can be supplied with SIRIM or TISI documentation support, CE marking and ISO 9001:2015 factory certification. English manuals, wiring diagrams and installation videos are provided for mill site teams.
Each unit is wrapped in waterproof film, fixed on a steel frame and packed in a fumigation-free plywood case suitable for sea freight to Port Klang, Penang, Bangkok or Laem Chabang. Spare mechanical seals, O-rings and a propeller are recommended as site stock. A 12 month warranty covers the motor and mechanical seal under normal operating conditions.
How many units does a cooling pond need?
As a rule, one 2.2 kW unit per 800 to 1000 cubic metres of pond volume, spaced along the long side and aimed to create a rotating flow pattern.
Can the mixer run continuously?
Yes, the motor is rated for continuous duty S1 with a 60 C medium allowance and built-in thermal protection.
