Chiller Plate Installation for Produce Processing Company in Chelsea, MA

The Problem: The produce company needed to be able to keep the temperature of foods consistent to promote freshness throughout the entire prep process. Products cannot warm up when going through the wash tank. The wash tank needed refrigeration over a cold plate chiller, where the water runs over the food being cut and prepped.

The cold plate chiller consists of a metal corrugated plate which stands vertically while water flows over the plate and cools it before going down to the area where the produce is washed. Water is then recirculated through the tank and dumped after the day for clean water.

The Solution: Mike Cappuccio and his team created a design so that the condenser outside of the building could function properly and regulate the water temperature of the wash tank. The plate was around 24 degrees with 50-60 degree water running over a 25 degree piece of ice, which drops down into the tank to constantly refrigerate the water.

Commercial Refrigeration for Ken’s Foods New Location

The Problem: Ken’s Foods needed a massive 450 ft by 80 ft walk-in cooler built in their new location -- old Barrett Warehouse Distribution Center. N.E.T.R., Inc. had to overcome several challenges in designing a refrigeration system that would accommodate the automated picking machines installed in the cooler. They also had to design a cooling system for the loading dock to keep the products cool at all times.

The Solution: Mike Cappuccio and his team used a software called The Hub to help determine the sizing specifications for this job. Ultimately, nine 15 horse-power condenser units and two 60 horse-power condensers were installed, along with thirteen evaporator coils to cool the entire walk-in cooler and loading dock properly.

J.P. Licks Gets Cooler & Freezer Installed in New Location

The Problem: Although the Orange Leaf Yogurt store was designed for frozen treats, the equipment left in the building was ill-suited for their needs. Finding the space for the walk-in cooler/freezer combo they needed was going to be a challenge. The only available space was in the basement, which had a low ceiling riddled with wires and piping that would have to be relocated to fit the new cooler and freezer units.

The building was equipped with a new furnace and an HVAC system that was only a few years old. However, the drop-panel ceiling that hid the large ductwork pipes did not fit J.P. Licks’ open-beam aesthetic and would have to be redone.

The Solution: Mike Cappuccio and his team at N.E.T.R., Inc. designed a solution for installing the freezer in the basement. The team had to reroute the existing piping and wiring in the ceiling to make space for the cooler/freezer combo. They built custom-length panels for both the cooler and the freezer, in addition to customized insulated floor panels to level out the uneven basement floor. N.E.T.R. Inc. also updated the commercial HVAC system for customer and staff comfort.

Siemens Medical Devices Gets New Freezer Refrigeration System

Problem: The current walk-in cooler and freezer combination for Siemens Medical Devices needed an upgrade. Siemens needed more freezer space for their samples and products, as well as a redundant system that would replace the staged system they were currently using.

Solution: N.E.T.R. Inc. built a three-pipe redundant refrigeration system with an entrance vestibule and a larger freezer space. This new freezer system has a hot gas line that will help to maintain the temperature inside the freezer within a tenth of a degree – which is required for storing medical samples.

Problem: Red Oak Sourcing’s server room required a commercial HVAC upgrade to keep the servers cool and protected. They wanted a slim, redundant system to ensure that the servers would stay cool in all weather conditions.

Solution: N.E.T.R., Inc. installed two Mitsubishi ductless air conditioning units in the server room, set to a lead-lag operating schedule that would protect the servers in-case of failure, extend the life of both units, and function in temperatures as low at -20 degrees.
