HVAC  & Refrigeration  Systems




Stainless steel jacketing over 1200° calcium silicate insulation on a boiler.


We provide insulation for heating and cooling piping, duct systems, boilers, breeching and chillers.  On cooling systems, insulation conserves energy and prevents condensation.  On boilers, the use of 1200° insulations with special jacketing enables them to operate much more efficiently.  We can fabricate a product to your specifications.

HVAC

HVAC refers to the Heating, Ventilation, and Air Conditioning system installed in a building to regulate temperature.  This includes air conditioning plants, chillers and ducting systems, which ensure the uniform transfer of the cold or hot air as the case may be, throughout the building.  Ductwork and piping -- hot water piping, chilled water piping -- needs insulation to maintain constant temperature levels (energy conservation), and to prevent condensation.

We properly cut, form, and install insulation.  We use boards, blocks, blankets and sheets to insulate ducts and equipment, including boilers, breeching and chillers.  In order to achieve noticeable energy savings, the insulation must be installed properly so it functions effectively.

REFRIGERATION

Refrigeration refers to the cooling portion of a heating, ventilation, and air conditioning system.  A refrigerant if circulated through the system expanding and contracting to maintain a constant temperature throughout the building.  Insulation is essential to help maintain temperature, minimize energy loss, and control condensation.


When piping and equipment operate at temperatures lower than the ambient air, moisture in the air will condense or freeze on or within the insulation surface – or on the cold pipe surface.  Unless the system is protected by sufficient thickness and by adequate vapor retarders, the insulation can become wet, causing corrosion, mold, or the insulation to become ineffective.
When installing thermal insulation on refrigeration systems, we meet exact specifications for application the insulation material and the construction of the vapor barrier system.  Our completed work allows for easy access for cleaning, maintenance, upkeep, and other necessary activities.


We use foamglass insulation for cryogenic-cold refrigeration lines and systems employing liquid nitrogen.  We can work in wet or dry workplace environments, above or underground.


If your maintenance program does not include being on the lookout for breaks in the insulation jacket or the vapor seal, and repairing those promptly, there is reason to suspect that moisture has penetrated the insulation and is now attacking the pipes.


The rusting is quickened by the presence of nitrates and sulfates (components of many types of insulation).  Aging systems should be investigated thoroughly with mechanical integrity inspection to prevent serious wear, tear and energy loss.


When insulation vapor seals become faulty with breaks and holes in the seals, moisture can accumulate under the insulation and causes the pipe to corrode until the pressure in the system exceeds the bursting pressure of the damaged pipe, creating leaks and a safety hazard.
