Core Advantages

Built for demanding industrial spaces

Explore the engineering behind the JH35LM / JH50LM metal evaporative cooler family.

Belt drive linking a separate motor pulley to the larger centrifugal blower pulley inside the cabinet
Air delivery

Belt-driven centrifugal airflow

A separate motor drives the centrifugal blower through a small motor pulley, a V-belt and a larger fan pulley. The double-inlet blower supplies high-volume air for ducted industrial cooling.

  • 35,000 / 50,000 m³/h models
  • Motor and blower connected by belt drive

Metal construction

A strong shell for industrial duty.

A rigid metal cabinet combines structural strength with resistance to corrosion and ageing.

  • Heavy-duty metal housing
  • Top or side discharge on the referenced models
Hot air passing through filter and wet pad, cooled air delivered by a centrifugal fan, with recirculating water and room exhaust
Evaporative cooling

Cooling happens at the wet pad.

Outside air passes through the dust filter and wetted cellulose pad. Water evaporation absorbs heat; the downstream centrifugal fan delivers the cooled air indoors, while an outlet allows room air to escape.

  • Pump → distributor → wet pad → tank
  • Fresh-air supply needs a room exhaust path
Conceptual push-button controller, LCD controller and electrical protection module
Control & protection

Control that fits your operation.

Select industrial buttons or LCD control, with overvoltage and overcurrent protection. Speed options depend on the configuration.

  • Single, dual or 16-speed inverter options
  • Optional scheduling and group control

Illustrations show operating principles. Components and available functions depend on the selected configuration.
