Our Heresite Coating Services

Our experienced Production team and facilities capability further made the coatings for wide range of market specific or large-sized process equipment viable.


We provide the highest standard of protective coatings quality for air conditioning and refrigeration systems which is tested to be corrosive-resistance when the HVAC-R equipment are placed and operating in a moderate or severely corrosive environments such as marine environments, swimming pools, wastewater treatment, agriculture, food processing industries.


The thin, flexible and durable protective coating film application to the HVAC Coil able to prolongs the lifetime of the equipment under harsh environment;  meanwhile maintaining the stable heat transfer. 


Air-Dry Coatings

Heresite VR-514  Air Dry Phenolics

International Oil Services Firms use Heresite

Radiators implemented on offshore platforms worldwide coated with Heresite in order to ensure 24/7 operations in harsh and corrosive salt & chemicals environments


Waste Water Treatments Facilities


In North America, the 2nd largest water treatment facility applied P-413 Heresite on blowers, air handling units and air-conditioning coils; whereas VR-514 was used to coat the miles of duct work in plant. These equipment are exposed to salt air, hydrogen sulfide and other gases at all times, yet the Heresite coatings has served the facility well in 10 years and above up-to-date.
