Control System

Spectrum Manufacturing wanted a control system that was more reliable and less complicated than the circuit boards currently on the market. After looking at many different options, a smart-relay with PLC (programmable logic controller) technology was chosen. PLC technology is used in many important applications that cannot afford to fail or have problems and is recognized as the most dependable controller available, . By writing their own program, Spectrum Manufacturing was able to tailor-fit the control system with their equipment, providing their dealers with a unit that was ahead of the pack. The smart-relay comes with a text read-out of all faults and operation modes. A screen mounted on the front of Spectrum equipment mirrors the text readout of the smart relay, allowing for quick inspection and diagnosis of the unit.

Noiseless Operation

Spectrum Manufacturing has gone the extra mile in making sure that their units are the quietest on the market. Isolating their compressor two times, muffling the noise of the compressor with a sound blanket, and using automotive grade, multi-layer sound deadening material in their doors. All these factors help these units achieve the reputation of being the quietest on the market.

Residential or Commercial

Spectrum Manufacturing has a solution for all job requirements. Whether it is just a three ton residential job or a 30 ton system for a commercial building, Spectrum Manufacturing is there to provide an answer to any heating or cooling need.

Spectrum Manufacturing offers a full line of geothermal heat pumps for commercial and residential applications. We have water to water units, water to air units and we also manufacture our own hydronic fan coils.

Dealers who have installed these systems are truly impressed, saying they are very quiet and reliable, and customers are very happy with their purchase.

That is our mission.
