New Light Commercial Products from Mitsubishi Electric

Get ready for some exciting, new light commercial products from Mitsubishi Electric Cooling & Heating! At Aireco Advanced Products Group (APG) we are proud to offer our customers the best in energy-efficient HVAC innovations for all types of applications.

SLZ-KF Four-Way Ceiling Cassette

The newest member of the M-Series, the SLZ-KF brings comfort to any light commercial application. With four-way vane control, occupants can select two-, three- or four-way airflow patterns. Each vane can also be adjusted individually. The optional 3D i-see Sensor®, which calculates the room occupancy rate, adjusts conditioning accordingly with direct or indirect airflow settings, offering 72 different combinations for comfort. The result is improved energy savings with a SEER rating over 19.8 and even temperature distribution. With the introduction of a 3D-turbo fan, the SLZ-KF’s sound level is supremely quiet, as low as 25 dB(A). In addition, the unit includes easy-to-clean, washable, 10-year filters with multi-stage allergen filtration.

Mechanical contractors will also be pleased to learn of the unit’s streamlined redesign compared to previous models. The temporary hanging hooks, captive screws and larger wrench-turning radius on piping make installing the unit overhead much easier.

MSZ/MUZ-JP Model 115 Volt Heat Pumps

Part of the M-Series product lineup, each 115 Volt Heat Pump system utilizes one breaker spot in an electrical panel versus the typical two breaker spots. A single-zone system, the MSZ-JP model indoor unit and corresponding MUZ-JP model outdoor unit are ideal for light commercial applications, such as hotels and restaurants. Available in 9 and 12 kBtu/h capacities, the system has a seasonal energy efficiency ratio (SEER) of 17.0, a heating season performance factor (HSPF) of 9.3-11.00 and an energy efficiency ratio (EER) of 9.9-12.0.

Additional Features

  • Quiet operation: as low as 22 dB(A) for the indoor unit
  • Low ambient heating down to – 4 degrees Fahrenheit
  • Wireless enabled (optional feature) with the ability to pair with kumo cloud® software and other thermostats when using the Thermostat Interface
  • Washable air filters and anti-allergy enzyme filter mechanisms
  • ECONO COOL mode delivers air at higher set point but in a swing motion, which is an energy-efficient way to make occupants feel cooler
  • 12-hour timer which allows for one ON/OFF cycle during a 12-hour period

CITY MULTI® for Grow Facilities

The legal marijuana market is expected to be worth $146.4 billion USD by 2025 and grow facilities are in high demand. With a multitude of medical uses and applications, companies like MariMed Advisors, a marijuana business consultant, are on the rise, helping growers legally design, develop and operate medical cannabis cultivation centers and dispensaries.

One of their latest developments is Kind Therapeutics USA, a grow facility located in Hagerstown, Maryland. While the building has diverse humidity and zoning requirements, mechanical contractor CARE Services Inc., based out of Williamsport, Maryland, knew CITY MULTI Variable Refrigerant Flow (VRF) from Mitsubishi Electric was a complementary system for the project. Below, the mechanical contractor explains why they specified CITY MULTI and the support they received from APG.

Why was Mitsubishi Electric VRF specified? 

From a system standpoint, we needed versatility. It’s a 130,000-square-foot, three-story building with two floors used for growing. We could not use ductwork and CITY MULTI VRF was an ideal system. We used a mix of the ceiling-concealed units and the wall-mounted indoor units.

The original plans actually called for a third-party VRF system. That brand had an equipment ship time of six to eight weeks and at the last minute, the first mechanical contractor could no longer work on the job. When MariMed Advisors called us for support, I immediately contacted Michael Stewart and Brian Maddrey from APG. We planned out the equipment and they put together a submittal package for me. Based on the success of other CITY MULTI projects we had done together, I suggested Mitsubishi Electric VRF to Kind Therapeutics. With equipment stocked at the Atlanta headquarters, we were able to get the product in a matter of days.

How was Mitsubishi Electric VRF favorable for this type of application? 

Certain strands of marijuana require specific amounts of humidity; certain strands require different temperatures. With VRF’s individual temperature settings, every area can have its own designated climate and comfort level. The zoning capabilities have been very beneficial in this application. In fact, we even installed Mitsubishi Electric units in areas that were not initially designed to be a part of the grow facility – like storage rooms. They’ve turned these different areas into part of the growing application and Kind Therapeutics has had even greater yields.

Ultimately, what equipment was installed?

We installed 88 indoor units and six condensing units in 2017. The building was fully operational in 2018 but they started growing the plants in 2017. As for controls, Kind Therapeutics has the AE-200A Centralized Controller and the Simple MAs for various rooms. A third-party ERV provides fresh air to the non-grow areas of the facility. Everything has been working great and the staff are happy with the individual controls and temperature settings.

How does APG provide technical support?

I may sound biased, but CARE Services is a Diamond Contractor® and we have been working with Mitsubishi Electric HVAC equipment since 2006. That said, the biggest benefit for me working on a CITY MULTI application happens to be their distributor, APG. The support I get from Tim Kemp, Matt Kemp, Brian and Mike is unparalleled. If I have a question, a problem, a concern, I get an answer. For instance, during the construction phase, I called up Brian to do a walk through, just to make sure we had another set of eyes on the project and he was there.

Every project I’ve ever done with APG, they’ve always had my back, no matter what.
