Charge Air Cooler

We supply a charge air cooler range, also known as an intercooler. Our supply of charge air coolers ranges in size depending on your engine size. We have options in small intercoolers for automobile engines and truck engines, and larger charge air coolers for marine diesel engines.

Here at Spiro-Gills Thermal Products, we are proud to represent GEA Maschinenkuhltechnik. We are able to supply:

  • Closed circuit coolers to meet the needs and requirements of the power generation and electrical industries
  • Pressure Gas Coolers to meets the needs of the compressed gas market. (Quantities of 5,000nm3/h up to abt 5000,000 nm3/h in the pressure range up to abt. 50 bars)
  • Recirculation coolers to meet the needs for air-cooled machines as well as middle size generators
  • Charge Air Coolers. These are custom made for all individual engine designs, particular criteria and varied operational conditions. As integral component of diesel and gas engines they work steadily on ships, rail borne vehicles or in stationary installations for engine performances>150kw

Fan Assemblies

We specialise in the supply of fan assemblies and are proud to represent Howden, Netherlands. Howden, Netherlands designs and supplies fan assemblies such as industrial cooling fans in various types:

  • D Series - axial cooling fans, designed to operate at peak efficiency at the most common duty points in field erected cooling towers and air-cooled steam condensers
  • E Series - the most widely supplied cooling fans by Howden, available in three different blade profiles, ENF, ELF and ELFA, for application in cooling towers, air-cooled heat exchangers or air-cooled steam condensers
  • K Series - cooling fans, designed for use in factory assembled cooling towers and air-cooled heat exchangers
  • SX Series - low-noise cooling fans, used in a wide range of cooling and ventilation systems that must meet strict environmental noise levels
  • Fan Casing - Howden patented 'Fan Casings' have a unique lightweight, double wall construction and are designed to match Howden cooling fans used in air-cooled steam condensers.

We are also able to supply other manufacturers of fans such as Hudson, Cofimco and many more.

Re-Tubing and Repair of Heat Exchangers

We provide a professional and dedicated service for the re-tubing and repair of heat exchangers.

Within our service for re-tubing and repair of heat exchangers, we carry out many repairs including the complete re-tubing of heat exchanger tube bundles. Our preference is to re-tube/refurbish in our own workshop where the work can be carried out under factory conditions. Where this is not possible, on-site repairs are arranged.

We supply helical high finned tube bundles in either welded finned tube, applied finned tube or extruded finned tube.
