Product Description

 

Product Description

Steam Coils are used in industrial air heating and processing and HVAC applications.
These coils make use of the steam's hidden heat (change of state) that is released when it condenses from a vapor to a liquid.
All steam coils are specifically designed with condensate management in mind.
Tube and connection size are combined to limit condensate retention in the coil, preventing water hammer while delivering even distribution of steam across the entire face.
Steam coil construction is available for high and low pressure applications and is a very effective way to heat air.

Standard steam coil type is a single tube design made from a 5/8″ or 1″ tube steam coil.
The steam supply and condensate return headers and connections are normally at opposite ends of the coil.
Uniform steam distribution to each coil core tube is accomplished by proper header assembly design.

A steam distributing coil is a dual-tube design using 5/8″ and 1″ tubes that are commonly referred to as freeze-resistant.
It is important to note that any steam coil can have condensed water freeze when exposed to freezing temperatures without properly draining the condensate.

This coil design utilizes a smaller inner tube with precisely spaced directional orifice-type perforations.
This arrangement helps 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 construction.
When made as a same-end connection, the header appears as a single large header, but is actually two headers in one.
Compartmentalizing the header serves multiple functions by providing for a supply and return.
The inner steam supply header warms 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.

TUBES
We make tubes of different diameters, with a greater number of thicknesses and different materials such as copper, stainless steel and cupronickel. The tube expansion, during the flaring phase, allows a perfect contact between the tubes and the fins and as a consequence it assures efficient thermal exchange.

COPPER - Copper tube                                          STAINLESS STEEL - AISI 316L tube                   CURRONICKEL - CuNi10Fe1Mn tube
 

FINSThe fins, made of aluminium, prevarnished aluminium or copper, are pressed by means of a particular ondulation that increases the thermal exchange between the air and the fin reducing the load losses on the air side and encouraging at the same time the flow of condensation or defrosting water.

The fins can also be made from 316L stainless steel for installations where the thermal exchange is in aggressive environments such as the food sector or exchangers used in salty environments.

The main geometries, achievable according to the chosen material, are reported following below; besides, according to the application chosen by the customer and to the thickness of the requested strap, it will be possible to make a major or minor pitch between the fins.

PLATESThanks to its accurate three-dimensional design and to modern punchers and numerical control bending machines, it is possible to make carpentry and structures of different sizes that can be adapted to any construction requirement of the customer.

Engineering Data

We have customized products for many customers, following are some projects we did before.
We can provide designing data and prodcution drawings.


We promise we use the design software sold by a well-known European HAVC software company.
Through 8 years of cooperation with them, we have designed, processed and exported heat Exchangers to various countries all around the world. 
All of customers feedback is that the actual cooling performance is almost the same as the theoretical design value.


 

Certifications

Leak test report:Before package, we will do the pressure test in the pool to check if the product leak.
(Process: Connect the inlet/outlet of the product to the tube s then put nitrogen in it, and put the product in water.
If there is no bubbling, there is no leak.)

Pressure Test Report:Under the pressure test, this product has no leakage; no visible abnormal deformation; no abnormal noise;
the test conclusion is qualified.
