Mission Critical HVAC Equipment

Mission-critical HVAC equipment for industrial and commercial applications is specially designed to provide reliable and precise environmental control in settings where equipment integrity and occupant safety are paramount. These systems are used in sensitive areas such as data centers, hospitals, and laboratories, ensuring temperature and humidity regulation, air quality, and equipment protection, even in challenging conditions. They are engineered for maximum reliability and redundancy to minimize downtime and maintain critical operations.

Process Chillers

A process chiller is a specialized refrigeration system designed to remove heat from industrial processes, equipment, or machinery. These chillers play a crucial role in maintaining temperature control in various applications, including manufacturing, chemical processing, data centers, and more. Their primary function is to lower the temperature of a liquid or coolant, which is then circulated through a heat exchanger to cool down a specific process or equipment.

DOAS & Make-Up Air Systems

Dedicated Outdoor Air Systems (DOAS) and Make-Up Air Systems are key components of industrial and commercial HVAC solutions. DOAS units are designed to provide fresh outdoor air separately from conditioned air, improving indoor air quality and energy efficiency. Make-Up Air systems ensure the replacement of exhausted air with fresh air, maintaining proper ventilation and pressure in industrial and commercial spaces. These systems are critical for ensuring a healthy and safe indoor environment, particularly in spaces with high occupancy or where pollutants are generated.

Industrial Dehumidification

Industrial dehumidification systems are specialized equipment that reduce humidity in large industrial and commercial spaces. They use dehumidifiers to cool and dehumidify the air, preventing issues like corrosion and mold growth. These systems are crucial in various industries for maintaining optimal conditions and preserving product quality.

Custom Air Handling Equipment

Custom air handling equipment is designed for industrial and commercial HVAC systems to meet specific requirements. These systems are tailored to the unique needs of a facility, providing efficient air distribution, filtration, temperature control, and humidity management. Customization allows for precise control of indoor air quality and environmental conditions, making it ideal for diverse applications such as data centers, laboratories, and manufacturing facilities, where standard HVAC solutions may not suffice.

Medium & Low Temp Refrigeration

Medium/low-temperature refrigeration systems are designed to maintain temperatures above absolute zero but below typical room temperature levels. Medium temperature ranges from around 0°C to 15°C, and low temperature involves sub-freezing conditions. These systems use vapor-compression refrigeration principles to cool environments, materials, or products within these specified temperature ranges, serving industries like commercial refrigeration, food processing, and pharmaceuticals, ensuring product quality and safety.

Tube Diameter

Use a caliper or tape measure to determine the outside diameter of the tubes.

If necessary, remove insulation to see the incoming and outgoing lines. Measure the diameter of the outside of the line to help determine connection size.

Standard connection types are MPT (male pipe thread), FPT (female pipe thread), and Copper Sweat Connection. MPT is threaded on the outside, FPT is threaded on the inside, and Copper Sweat is used for soldered connections

Fins per Inch

Using a ruler, count the number of fins on the coil within one inch. Normal fin counts will be between 4 and 14 FPI.

Fin Length

Measure in the direction of the tubes, regardless of which direction the tubes are running.

Fin Height

Measure in the direction of the fin.

Single, Double, and Half Serpentine

Rows are counted in the direction of airflow, no matter how the coil is installed. You can count rows by looking at either the header end or the return bend end of the coil. Note that headers or return bends may not be evenly spaced across the coil.

Fluid coils—hot water, chilled water, and glycol water—regulate building air temperature by heating or cooling air in Air Handling Units (AHUs). Constructed with multiple rows of tubes, typically copper, these coils efficiently transfer heat between air and circulating fluids. They are vital for year-round comfort, accommodating diverse fluids like glycols and thermal oils for varied HVAC needs.

Condenser coils transfer heat from refrigerant vapor to the outdoor air, ensuring efficient cooling in HVAC and refrigeration systems. Constructed from materials like copper or aluminum to maximize heat transfer, these coils are vital for maintaining precise temperature control in industrial and commercial environments.

Steam coils utilize the latent heat of steam, released during condensation from vapor to liquid. They feature efficient condensate management to prevent water buildup and ensure uniform steam distribution. Available in configurations for high and low-pressure applications, steam coils are highly effective for heating air in a wide range of environments.

Evaporator coils absorb heat from indoor air to cool and dehumidify spaces by evaporating refrigerant from liquid to vapor. Located indoors, these coils are essential for maintaining comfortable environments in industrial and commercial settings, offering excellent performance in cooling, process cooling, and dehumidification applications. They are versatile for use in Air Handling Units (AHUs), central systems, or duct installations.
