Coils
We offer a wide range of battery customisation options: airtight coils, materials used, design and testing, accessories, surface treatments, ...., etc. Don't hesitate to contact our teams to work together to find the best solution to your needs.
Air tight coils
The tubes are not expanded in the tubesheets, to allow free expansion of the tubes during changes in temperature.
The resulting annular space means that there is no seal between the process air (on the fin side) and the outside air.
This results in leakage to the outside if the air is at positive pressure, or on the contrary, incorporation of outside air into the process if the process is at negative pressure.
Surface treatment
Certain operating conditions require enhanced protection of the coil's surfaces and structure.
The right combination of base materials and coatings can guarantee reliability and durability, even in the most aggressive environments.
- Hot dip galvanised
- Heresite® P-413
- Blygold®, Blygold HT
- Polyurethane paint
- Cataphorese
- Passivation
- External passivation by dip
Main accessories and options available
Condensate drip trays can be integrated into the bottom frame or even halfway up.
They are designed for integration into the machine or to be connected to ducts, including airtight versions.
The position of the drain can be customised. They can be fitted with electric defrost elements.
They are available in 8 versions to cover all possible drain and frame design configurations.
- Galvanised steel
- 304 stainless steel, 316 stainless steel
- Copper
The droplet eliminators prevent entrainment at high air speeds (> 2.8m/s). They are available in a range of materials depending on operating conditions.
- PPTV elements spaced 30mm apart
- Aluminium or stainless steel frame
Integrated defrost systems
This is necessary if frost is likely to form on the fins.
Coils can be fitted with :
- Integrated coil
- Electric defrost
- Hot gas defrost
- Removable lifting lugs
- Intermediate structural reinforcements
- Manifold supports
- Protection grid
Design codes - certification
Our partners are ISO 9001:2015 certified. Thermodynamic calculations are carried out using software developed in-house, adjusted and confirmed by measurements taken in their in-house measurement laboratory, which complies with ASHRAE standards.
Our partners are AHRI-certified, which guarantees the performance of the water heat exchangers. Each coil is manufactured in compliance with CE directives.
Coils can be built to ASME VIII div.1 (with or without U-stamp), EN13445 or any other design code on request.
Our partners have brazing and welding qualifications to ASME IX, EN9606, EN15614, EN13585 and EN13134.
Heat exchangers can be designed and manufactured to withstand earthquakes or other accelerating conditions.
