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.

Problem: The Campion Center home for retired Jesuit priests had no central air conditioning. The residents suffered from hot summers and the high cost of running window ACs in such a large building.

Solution: N.E.T.R. installed four separate systems: three full American Standard central AC units with ductwork and one full heat pump. Three hot water heating coils were also established for future upgrades to the heating system.

Problem: Cambridge, MA local convenience store and deli, Montrose Spa, had an outdated, obsolete refrigeration system that was costing thousands of dollars in repairs and monthly expenses.

Solution: N.E.T.R. removed the entire outdated system and installed brand new Zero Zoned commercial refrigeration system, which updated the appearance of the store, saved the owner in energy costs, and provided a more environmentally-friendly solution for cooling his products.
