PRODUCTS  

FLUID COILS
Cooling applications are most commonly used in chilled fluid systems for comfort conditioning of a forced air stream and in process systems for dehumidification processes. A large variety of drainable circuiting options makes this a good choice for most general heat transfer applications. For use with water, glycols, brines, thermal oils or ammonia.

Heating applications are most commonly used in hot fluid systems for comfort conditioning of a forced air stream and in process systems for drying processes. The collector header design with internal baffles provides circuiting flexibility while eliminating the need for return bends, while the splayed header design uses return bends for circuiting in lieu of a collection header. The term "splayed" means that the coil headers are offset outward from the coil tubes. The splayed header coil always has same end connections.

Cleanable applications are commonly used where mechanical cleaning of the coil tubes is required. One and two row coils are furnished with removable brass threaded plugs on either or both ends.  Multi-row coils utilize a removable steel head plate in lieu of coil headers. This plate contains baffles to provide coil circuitry and is removable for easy access to coil tubes. Cleanable options include cleanable from the supply connection end, cleanable from the end opposite the supply connection or cleanable from both ends.

BOOSTER COILS
Duct-mounted reheat coils which are used in general heating applications. Booster coils are provided with a variety of casing configurations including fully flanged, slip and drive or end plates only

STEAM COILS
Standard or steam distributing construction is available for high and low pressure applications.

Standard steam type is the basic 5/8" or 1" tube steam coil, known as the single tube design.  The steam supply and condensate return headers and connections are normally at the opposite ends of the coil.  Uniform steam distribution to each of the coil core tubes is accomplished by proper header assembly design.  The steam supply connection should be located in the center of the header, with a perforated plate type baffle located directly behind this connection.  Properly sized orifices are located in each of the core tube entrances into the header.

Steam distributing 5/8" & 1" tubes are the "freeze resistant" coils, known as the dual-tube design. It is important to note that any steam coil can freeze when exposed to freezing temperatures without the proper drainage of the condensate!  This coil design utilizes a smaller inner tube, with precisely spaced, directional, orifice type perforations. This is to help direct condensate flow to the return header.  The steam supply, condensate return headers, and connections may be fabricated as a same-end or opposite end orientation.   When made as same end connected, the header appears as a single large header, but is actually two headers in one.  Compartmentalizing the header serves multiple functions. As well as the supply and return, this compartmentalizing has the inner steam supply header warming the condensate return, and allows same end connected single and two row coil construction. This eliminates the unwanted core tube return bends on a steam coil.

REFRIGERANT COILS
Single, dual or quad compressor circuits allow precise capacity control. Unique interlaced circuiting options assure uniform refrigerant distribution over the entire face area of the coil. Wide fin spacing availability reduces the affect of frost build up on low temperature applications. For use in central systems or duct applications.

CONDENSER COILS
Condenser coils are hide side refrigerant coils individually engineered to meet unique requirements. Fin spacing, circuiting and fin design can all be varied to assure performance, air and tube side pressure drop limitations are maintained.

SPECIAL COATINGS (please see our section on corrosion)

These are only some of the specialized coatings available. Please contact us with your requirements.

Water-Based Black

This is an acrylic water-based, low-gloss coating that is sprayed on coils for cosmetic purposes only.  The most common application is for outdoor condensers.  This coating has a 500 hour QUV Test specification of 1.5% minimum gloss loss and a 200 hour salt spray test (ASTM B117) specification of no blistering on unscribed test.

Baked Polyester Enamel - FDA Gray and Satin Black

We offer two baked polyester enamel coatings that can be applied by either dipping or spraying.  Both are used for corrosion protection.  The FDA Gray meets the requirements of the US Federal Register and Food and Drug Regulations, Title 21, Chapter 1, Paragraph 175.300.  

Electrodeposition or E-coat

This is a water-borne cathodic epoxy electrodeposition coating that meets Title 21 for NSF applications.  It is both durable and flexible, has excellent heat transfer properties, and is resistant to various chemicals.  It also allows for a very uniform finish throughout the coil.

Baked Phenolic (Heresite, P-413)

Baked Phenolic coatings offer excellent chemical resistance to a wide range of acids, solvents, and mild alkalis.  They also have excellent temperature resistance and good heat transfer properties.  The cleaning, application, and curing processes ensure a durable and flexible coating that meets the requirements of the US Federal Register and Food and Drug Regulations, Title 21, Chapter 1, Paragraph 175.300.

Electro-Tin Plated

This is a tin coating that is electrically adhered to copper.  It is normally applied directly to copper hairpins before the coil is assembled and brazed. It provides excellent protection against corrosion and does not hinder the brazing process whatsoever.  This coating meets Military Standard T-10727B and is generally used in combination with anodizing for military applications. 

Anodizing (Iridite)

This is a chemical conversion process used on aluminum and various aluminum alloys.  It is performed on these metals to give them added corrosion protection when a coating is not employed.  It is also used to improve the adhesion of paints and finishes.  This coating meets Military Standard C-5541.

 Hot Dip Galvanizing

This is a zinc coating that is generally used on steel for corrosion protection and improved heat transfer.
