-20 Degree Refrigerated Warehouse – North Bergen, New Jersey

Project Title:  Tree of Life -20 degrees Refrigerated Warehouse

Cost: $400,000.00

Job Location:  North Bergen, New Jersey

Design Criteria:  Integrate into an existing warehouse a new 4000 square foot freezer connected to an existing 3000 square foot refrigerated box.  Unlike typical applications this box cannot be supported by the roof of the building, and the box installation must take place without interfering with ongoing operations.

Description of Installation: A insulated concrete pad with vapor barrier was poured over a network of  electric heaters so that the concrete floor of the box and building would not freeze and crack.

Steel framing was erected to support the freezer.  The box was then erected over the steel. Sodium lamps were installed for the lighting since they operate at very low temperatures. Drain lines were installed and heated so that the condensate wouldn’t freeze.

3 22 horsepower Condensing Units were placed outside the building and piped to 3  Evaporators.  R-404A was selected as the refrigerant since it is a nonchlorinated ozone friendly gas.

Water Cooled Chiller Replacement – Ridgefield, New Jersey

Project Title: Water Cooled Chiller Replacement

Cost: $60,200.00

Job Location: Ridgefield, New Jersey

Design Criteria: Replace an existing chiller system with new equipment that would fit through the restricted access to the basement.  Finding equipment that would fit was our foremost concern.  Energy efficiency was identified as a major priority.

Description of Installation: 2 25-ton water cooled chillers were installed with brazed plated heat exchangers.  These chillers were selected due to their weight , size, and ability to operate at reduced capacities to conserve energy.  The two chillers are controlled by a Control Panel equipped with lead-lag control, 7 day time control, and water temperature adjustments.

The old chiller was dismantled and removed in sections, the new chillers were rigged down the stairs with a chain fall  and set into place.  A new water tower was set on the roof and interconnecting water piping was installed as well as a new pump and pump control.

Hot Water Boiler – Ridgefield, New Jersey

Project Title:  Hot Water Boiler

Cost:  $19,750.00

Job Location:  Ridgefield, New Jersey

Design Criteria:  Replace an existing hot water boiler on an emergency basis, provide make up air for combustion, integrate a control package, and provide adequate drainage for pressure relief discharge.

Description of Installation:  We removed from location the existing boiler and rigged into place  a H.B. Smith 1,200,000 Btu input Boiler with a compatible control package that would interface with the existing building controls.

Our Installers connected gas piping, supply and return water piping, breeching, water feed piping, recommissioned a floor drain and installed drain piping for pressure relief.
