Water Tower Pumps and Controls | Pumping Systems - Water towers maintain a ready limited supply of water for communities in the event the water main goes down. Many towers are used for emergency situations for the fire department to have water for fighting fires and for water fire suppression systems to have a supply of water for the emergency if it should arise.

Ceiling Fan in a Garage | HVAC Airflow – This ceiling fan keeps the air moving in a large garage where repairs are made to heavy machinery. In addition to providing a level of comfort by keeping the air moving in the shop the ceiling fan also helps to keep noxious fumes at higher elevations and moving towards the exhaust fans so the noxious fumes from heavy equipment can be removed from the shop area.

Heat Trace Tape Control for HVAC Piping - HVAC Piping systems, especially in the Northern regions, need a way to freeze protect piping the runs outdoor which is a necessity in many different HVAC application. To protect HVAC piping from freezing heat trace tape is wound around the pipe and controlled by an outdoor thermostat or temperature control that energizes the heat trace tape and keeps the pipe from freezing.

Domestic Hot Water Mixing Valve and Domestic Storage Tank - This domestic hot water mixing valve offers a way to temper the hot water coming from a hydronic hot water loop and boiler. It is very important to maintain the appropriate and desirable temperatures of water used for domestic water use.
First, you want to maintain a safe temperature so people are not scalded by extremely hot water temperatures. Once the temperature is safe it needs to be reliable. Since the boilers operate or are on standby 24/7 - 365, the availability is there to reliably make domestic hot water on demand. (more…)
Infrared Heating System
Infrared Radiant Heating systems provide comfortable heat in larger areas and spaces such as garages, warehouses, and other open spaces where other types of heating systems are not practical or efficient. Infrared radiant heat works through thermal radiation transmitting heat to large objects including floors and walls.
These large objects heat up through thermal radiation and then release that heat to the surrounding air through convection making the open space or open area comfortable for the occupants. (more…)
HVAC Reznor Heating System – this Reznor unit heater provides heating for warehouses, garages, and other open spaces which can be heated with unit heaters. Unit heaters are ideal for big open areas which need heating without ductwork being used to channel the air into the open space. (more…)
This chilled water unit is a new ammonia chiller. This unit is also unique in that it has no compressor. Instead, it uses the chemical properties of ammonia and heat from natural gas to condense the refrigerant which is ammonia. A chiller provides chilled water to a chilled water loop. (more…)
Hot Water Boiler Economizer PreHeater | Energy Efficiency - This is a hot water economizer and is a big preheater for domestic hot water use. This hot water boiler plant serves a large community for heating and domestic hot water use. Domestic hot water is used for showers, washing dishes, laundry, etc, etc, etc….
The cold water supply from the city is routed through the economizer to be pre-heated before it goes through a heat exchanger and then the hot water storage tank. (more…)
Variable Frequency Drives VFDs | Energy Efficiency - In HVAC variable frequency drives add energy efficiency and precise control for fans and pumps. The VFDs offer demand control for airflow and water in chilled water systems, hot water systems, and air handling systems. Additionally, they are used to control airflow in a variable air volume system. More on how VAV boxes work.
VFDs require inverter duty motors and variable frequency drives can be purchased for three-phase and single-phase applications although the vast majority of variable frequency drives are used in commercial three-phase applications. (more…)
VAV Air Handlers are ideal for providing zones in a commercial building. Office space typically has several offices and open areas that need to be conditioned for the comfort of the people working in those areas or offices. By installing VAV boxes and zoning the ductwork from those VAV boxes these areas and offices can be kept comfortable using a VAV air handler system. More on how VAV boxes work. (more…)
