Coil Corrosion
Coil Rusting
Mould & Bacteria
Heat exchangers are susceptible to harsh environments, over time, contaminants can corrode the heat exchangers. This causes the outdoor condenser coils and indoor evaporator coils to degrade its cooling performance, leading the high head pressure, loss in efficiency, dirt build-up causing microbial contamination resulting in poor indoor air quality, bad odor, increase in power consumption, pin hole leakage, and eventually, compressor failure.
The Solution
Protect your coil easily with DTM-TiO2 coating providing long-term
- Anti-Microbial protection
- Anti-Corrosion protection
Improve air quality, increase cooling efficiency, reduce electricity consumption, ease of maintenance, and increase equipment lifespan.

Frequently Asked Questions (FAQ)
What is the anti-corrosion properties of ERCA coating on the following materials: aluminium, copper, galvanised steel?
Our solution is ASTM Tested with good anti-corrosion properties for all 3 metal substance.
Special care to be taken for galvanised steel application and copper to make sure surface is free from oil before coating.
Will the heat transfer efficiency be affected after coating?
The effect is minimal due to the thin layer of coating.
Can the ECRA Corrosion coating be used in Micro Channel fin design?
Yes, DTM Spray coating process is recommended. Using a good spray technique with multiple coating layer. Spray coating knowhow will be transfer to client.
Is there any pre-treatment required before coating?
Coil need to be degreased, clean, dry, free from fin press oil and dust before coating. New unit direct from factory need only air spray to remove dust. Old unit need to be wash with degreaser and dry before coating application.
What is the volume of usage for the coating area?
ECRA SHM Dip coating covers 50 square meters of coil surface face area per litre .
ECRA DTM TiO2 Spray coating covers 2 square meter of coil surface face area per litre.
Any detailed study done with Test Report for coated coil and uncoated coil?
Many of our OEM customers have done studies but they are IP for that specific customer.
After coating the efficiency improve or is the coating a preventive measure to prevent future degrading?
Dipped coils show minimal initial efficiency loss (6-8 microns Dry Film thickness)
Sprayed coils have a thicker Dry film thickness and could cause an initial loss of 1%.
This again is initial efficiency loss and during operation the efficiency is maintained where a corroded coil loss huge efficiency.
Where is the Country of Origin?
Australia Sydney.
How long does it need to dry the coil after coating?
Both ECRA-SHM dip and ECRA-DTM spray need to be initially air dried and then depending on application oven cured.
ECRA-SHM dip needs to be baked for 30 minutes at a minimum of 130 °C
ECRA-DTM spray:
Indoor Evaporator coil oven cured for 30 minutes at a minimum of 110°C
Outdoor Condenser coil ambient air drying coil for 24 hrs.
What are the maintenance required after coating?
Easy maintenance by flushing the coil with clean water when needed. Do not used harsh acid or alkaline cleaners. Quarterly maintenance for coastal / hostile environment is recommended.
What is the Shelf life of the coating?
Shelf life of 5 years with proper storage condition away from direct sunlight and heat. Once the lid is open, use the coat within12 months. Mix contents of 10 litre pail thoroughly before use
Is the coating considered as Dangerous Goods?
No, our products is environment friendly water-based coating. Product is classified as Non-Dangerous Goods and can be ship easily by Sea and Air shipment.
What are your project reference?
We supplied to OEM Manufacturers worldwide for 15 years.
Our customer of DTM Coating offers 5 years rust protection warranty with coastal installation
What is the energy saving % improvement after clean, coat of outdoor condenser coil, indoor evaporator coil and Combine both indoor and outdoor?
Every unit would be different.
For example, after cleaning how dirty was the coil prior to cleaning
A coil uncoated could lose 8~10% plus year-on-year efficiency without being coated.
Combination of corrosion/contamination I would estimate could easily cause 10% efficiency loss
Any detailed study on ROI payback for coating the coil?
Depending on the price of application ROI should be 12-18 months again depending on cost of energy as well.
Will training be provided to use the coating?
Yes, training on customer site will be provided to help train the local staff and develop production Standard Operating Procedure for proper application of the coating.

Chiller Plant Optimisation & Control
We have a complete hardware and software solution that enables optimisation and control of your chiller plant, enabling up to 40% annual energy savings.
In commercial building, HVAC is by far the most energy intensive system, accounting for close to half of the total energy consumption.
For this reason, every efficiency improvement in HVAC performance can significantly reduce the energy profile of the building, turning HVAC optimisation into a value generating opportunity.
Typically hidden away in plant rooms, HVAC systems can be complex, challenging and are frequently overlooked. No wonder that energy saving opportunities are missed in this complex technical arena.
Dedicated specialized control solutions are required to manage HVAC systems correctly and efficiently. By optimising the operation and maintenance of these systems, it is indeed possible to capture the true energy reduction potential available and to manage this over time.
The plant room can be considered the HEART of the HVAC system within the building. It is typically where hot and cold water is created for distribution to other HVAC subsystems throughout the building. Typical HVAC equipment in plant rooms include chillers, heat pump and boilers; heat rejection systems: air, water, ground source; and distribution equipment: pumps, valves, and pipework.
Chillers and heat pumps are the heaviest energy using components, accounting for 78% of total plant room energy consumption. Optimisation of the energy used within the plant room is therefore critical to the overall building energy profile, and can only be effectively managed by suitable experienced technical experts.
We have a dedicated plant room optimization solution and control software – capable of delivering efficiency beyond the individual components.
- Differentiates from traditional static BMS, achieve optimization in REAL TIME.
- It utilizes on-board, real-time analytics, diagnostics and M&V system to continually readjust chiller plant for optimal performance.
