| The Diversified Heat Transfer Group (DHT),
manufacturers of Lindy Coils, produces over 5,000 coils to original
OEM specifications. When provided with the make and model number of
the boiler, we can cross-reference to the appropriate coil design, and
deliver a replacement coil in less than 24 hours or less. DHT also
stocks 4 standard Lindy coils designed to match the individual requirements
of common boiler types.
|
Lindy coils are the result of experience
and pioneering research, and are designed to fit the construction and
space conditions of every low pressure steel boiler built and installed
within the last eighty years.
Coils are made from the copper, fin/smooth tube, cupro-nickel, stainless
steel and a variety of other materials upon customer request.

Capacity

 Ratings of domestic tankless coil units
are based on the number of apartments. We have added 20% to the regular
requirements to account for washing machines. Dishwashers also add a
tremendous load during peak draw periods. If the building has dishwashers
in 30% of the apartments or less, each dishwasher should be counted
as a one-half an apartment. If greater than 30%, each should be counted
as a full apartment. Should any of the have extra baths, the water load
is increased by one-half of an apartment for each extra bath. No more
than 5 GPM flow can be expected from 1/2" I.D. (5/8" O.D.) tube without
forfeiting pressure (volume) at fixtures.
Where more than 5 GPM flow is required,
heaters should be constructed of two tube delivery (double coil). Where
more than 8 GPM is required, three tube (triple coil) construction should
be specified, with proportionate increases calling for 6,8,12,16 and
up to 24 tube delivery. These selections are for large residences, apartment
houses, and public housing projects. For commercial buildings, schools,
laundries, restaurants, clubs, etc., please consult us directly.
