Radiator Types


Hitech has the capability of manufacturing the above types of radiators with the following material and technical specifications

CONSTRUCTION OF RADIATORS

• Hi-tech can manufacture 520/380/3551300 mm wide radiators using cold rolled carbon steel (CRCA) as well as stainless steel sheets of grade 304L and 314L The standard thicknesses of sheet are 1.00mm and 1.2mm thick. Special customer request of higher sheet thickness can also be incorporated upto 1.6mm thick.
• The infrastructure at hi-tech can manufacture Radiators with center to center distances starting from 1000 mm to the largest of 4500 mm.
• The elements are held in position with bracing straps or rods Hi-Tech can provide 80 mm / 1Omm dia. bright rod or 25mm x 6mm mild steel flat for the purpose of bracing as per DIN 42559.
• The distance between the elements i.e. pitch that hitech can manufacture are 38mm / 4Omm / 45mm / 5Omm and 55mm.
• Hitech has tooling to manufacture radiators with Header of 88.9 mm OD (80mm NB) and 114 mm OD (100mm NB) as per DIN 2394.
• Specific client requirements as per IEEMA or DIN standards regarding accessories can also be incorporated. Fan support brackets can also be provided on the radiators.

Hi-Tech can offer radiators with a Varity of internal and external coatings.

EXTERNAL COATING:

• Surface Treatment: radiators are grit blasted after pressure testing. Grit blasting ensures that the entire surface area is cleaned and no contamination, oil traces or rust is left out The grit blasting process also gives the necessary profile which facilitates paint adhesion on metal. The radiators are grit blasted to Sa 2 1/2 as per ISO 8501 or SSPC-SP-10.

• Hi-Tech offers the following paint systems as per customer requirement.

• Radiators externally coated with synthetic Enamel paint, final paint shade as per client specifications.
• Radiators externally coated with Epoxy paint, final paint shade as per client specifications.
• Radiators externally coated with Zinc rich primer+ Epoxy MlO + polyurethane paint, final paint shade as per client specifications.
• Water based paint system to suite customer requirements.
• Spray galvanized Radiators and coated with any of the above mentioned paint systems.
• Hi-Tech can offer paint system that can fulfill any of the ISO 12944 Global Corrosion standard.

INTERNAL COATINGS: Hi-Tech offers a verity of option for internal coating of radiator.

• Surface Treatment: The radiators are first thoroughly cleaned with wire brush followed by dry air purging to ensure all the dust is thrown out of the radiator. After dry air purging an electromagnet in inserted in the header pipe to ensure that no metallic contamination is allowed to remain inside the header pipe.
• Radiators internally coated with phenolic resin based hot oil resistant varnish with a temperature index of 120 °C.
• Radiators internally coated with primers.
• Radiators internally coated with Transformer Oil.
