Due to our plentiful stock of raw materials as well as a mission to
accommodate, DHT offers special 24 hour, 2-3 day, 5-7 day shipments for
emergency situations and 2 to 3 weeks represents our standard ship
cycle.
QUALITY ASSURANCE:
Quality Assurance is guaranteed at DHT. All coils are tested with water
or nitrogen to at least 300 psi for 30 minutes. First, all units are
examined to insure the correct tolerances. Finally our QA engineer
verifies that each coil is built to specifications. ARI and ASME
available. |

Water Coils
Chilled and hot water coils available |
| . |
 |
Steam Coils
Standard steam and steam distributing coils available.
Coils using over 100 psi steam require 90/10
cupronickel tube. |
|
|
 |
Direct Expansion
Coils
Evaporator and condenser coils available |
| . |
 |
Specialty &
Custom Coils
Coils can be manufactured using various materials to
meet the design application. Application requiring
1000 psi steam or 3000 F dry bulb are not uncommon. |

Quality
is Built into every Coil
|
| Tube materials consist of
copper, 90/10 cupronickel, stainless steel or carbon steel. Standard diameters range from 3/8" to
1" O.D.; using 0.018" to 0.065" wall.
Casings are constructed of galvanized, copper,
stainless
or carbon steel plate. 16 gauge plate is standard, but
thickness up to 8 gauge is available.
Fast Turnaround is a commitment at DHT. Our years
of experience in heat transfer products and large inventory
of raw materials enable us to offer the most efficient
service and support in the industry.

|
Fins can be either plate or helical (I-footed or
solder bonded). Materials consist of aluminum, copper or carbon steel. Fin spacing is available from 4 to 14 fins per
inch.
Quality assurance is guatanteed at DHT. All coils
are tested three times before leaving our facility. First,
all material is examined to insure specified tolerances.
Second, all coils are hydrostatically tested to 300 psi.
Finally, our QA engineer verifies that each coil is built to
specifications. |
