LSWE

The LSWE’s Thermal-Pak II Coil now features Cross Cool™ Internal Tube Enhancement, increasing the internal heat transfer coefficient of the coil and thus the cooling capacity of the unit. The LSWE offers the most models and box sizes in all EVAPCO products and is designed with IBC Compliant Construction and CTI Certified Performance.

  • Suited for indoor and ducted layouts, ideal for exact replacement projects
  • Ranging in capacity from 276 to 15,670 MBH
  • IBC Compliant – Independently certified by the International Building Code to withstand seismic and wind load forces in North America; available with IBC Upgraded Structural Design to meet the strictest of building requirements
  • Independently certified by the Cooling Technology Institute
  • Available with FM Approved Construction
The process fluid circulates through the coil of the closed circuit cooler. Heat from the process fluid dissipates through the coil tubes to the water cascading downward over the tubes; simultaneously, air is blown through the unit by the fans, and travels upward over the coil opposite the water flow. A small portion of the water evaporates, removing the heat from the system. The warm moist air is forced to the top of the closed circuit cooler by the fan and discharged to the atmosphere. The remaining water falls to the sump at the bottom of the cooler where it is re-circulated by the pump up through the water distribution system and back down over the coils.
  • Thermal-Pak II Coil

    EVAPCO's Thermal-Pak II coils design assures maximum cooling capacity. The airflow through the coil is counterflow to the fluid flow, providing the most efficient heat transfer process.

    • Elliptical return bends allow more circuits per coil bundle
    • Coil located in airstream increases dry bulb switchover temperature
    • CrossCool Internal Tube Enhancement increases fluid turbulence
