Sand-Blast Grids

API Heat Transfer has developed a line of Covrad sand-blast grids that are made to protect your cooling package investment. Sand-blast grids consist of a steel hexagonal inter-locking matrix that mounts between the radiator core and the blower fan, protecting the core from “sand-blast erosion” in harsh environments.

Features.

  • Robust patented construction with mechanically interlocking tabs
  • Cost effective solution to extend service life of cooling package
  • Includes Steel “U-Edging” welded around the perimeter of the grid
  • Mounting provisions designed to match any radiator
  • Custom designed to fit any radiator size & configuration
  • Designed to minimize space required…only 0.50” deep
  • Can easily be retrofitted into existing installations
  • Durable EDP coating

Advantages.

  • Absorbs impact/energy of fan-propelled particles before they contact core
  • Protects core from erosion resulting from sand abrasion
  • Very low external static resistance to cooling air flow

Benefits.

  • Negligible effect on cooling airflow
  • Eliminates high proportion of “sandblasting” erosion of radiator core in blower fan applications
  • Extends useful life of radiator compared to unprotected cores
  • Eliminates costly downtime from replacing radiator cores

Uses.

  • Specify as “standard” or “optional” value-added component
  • Specify anytime equipment is used in high sand/dirt/debris site conditions having blower fan arrangement
  • Standard product consists of 40″ x 40″ and 48″ x 48″ kits, which include u-edging finish trim for perimeter

Remote Cooling Kits

Due to the constraints of space and because of thermal considerations in many environments, an increasing number of commercial power generation installations require the cooling equipment to be remotely located from the generator room.

The kits can be cooled by a separate secondary water source, such as a cooling tower or remote radiator, and can be offered to withstand the secondary water source up to 160 meters above the engine. This makes them ideal for cooling engines situated in the basement of tall buildings, where the radiators need to be on the roof.

Base-frame mounted remote cooling kits consist of:

  • Water-cooled charge air coolers
  • Jacket water heat exchangers
  • CCW and JW header tanks
  • All pipework to the engine (jacket water optional)
  • A fuel cooler can also be added, if required
  • Coolant circulation pump for remote radiator loop can also be provided

Turnkey Genset Radiators

Our line of Covrad Turnkey radiator cooling packages feature our unique high-performance cores and low horsepower fan engineered into a compact envelope. Choose from pre-engineered models or request a custom sized solution based on your specific rating and site conditions.

RhinoDrive™ Turnkey Engine-Driven Radiator

Specify a RhinoDrive™ turnkey engine-driven radiator from API Heat Transfer for your next high horsepower (3MW+ direct drive off engine) gen set installation to avoid using costly remote radiators with electric motor driven fans.
