Custom and Modular AHUs Meet Your Commercial HVAC Needs
Coward Environmental Systems, Inc. (CESI) assists our clients in selecting the right air handling systems and components for their projects. Specifying the appropriate products in an HVAC air handling system is the only way to ensure top performance. CESI sales engineers ensure that our clients understand a product’s requirements and specifications. We also make sure these AHU and companion systems efficiently address other indoor air quality issues, including temperature, humidity, air velocity, humidity, noise, ventilation, and the presence of particulates, VOCs and pathogens.
Our experienced sales team helps clients with every detail of the entire selection process – from design to production. CESI brings together the strictest standards of project management, proven know-how, and decades of commercial HVAC and air handling experience. We’ll recommend an air handling unit to ensure HVAC systems run more efficiently, improve indoor air quality, and reduce maintenance requirements.
Identifying the Best Options
A custom AHU (air handler unit) is a vital component of any commercial air-side heating, ventilation, and air-conditioning system. AHUs regulate and circulate outside air to help all other systems heat, cool, humidify, dehumidify, and filter air, regardless of the fresh air requirements of the facility.
Many projects require a large outdoor AHU, often called a packaged unit. When these are installed on the roof, they’re referred to as a rooftop unit (RTUs). Both types of installations may be called makeup air units (MAUs) when the units are dedicated to supplying 100 percent outdoor air. In this application, the systems only condition air from outside the facility instead of the recirculating interior air, or mixing the two. AHUs that recirculate indoor air are smaller and are used in localized areas. These AHUs are often called terminal units.
AHUs can be located in basement levels, on roofs, or even the floors within a building. Because AHUs are used for large commercial structures, each AHU is often designated to a specific zone within a facility, such as particular floors, a side of the building, or limited to a purpose-built area such as a laboratory, office space, or public spaces. This multiple zone strategy means that it is common to find various AHU’s throughout a building.
CESI is the area’s most experienced expert in air handling units. We offer modular air handling systems for air conditioning, ventilation, heating, cooling, low pressure, and high-pressure systems. CESI is proud to offer high-end air conditioning and ventilation solutions, including a series of custom and modular air handling units.
The materials and components used in our selection of AHUs feature long-lasting, high-quality construction, and a wide airflow (CFM) range. Some commercial buildings need to control humidity, so sensors can be added at the outlet of the supply AHU to measure and control the amount of moisture.
FlexAir manufactures air handling units to fit each project specifically. Custom features can include cabinet construction, materials, shapes, and sizes, to coils, filters, and energy recovery devices. It can build modular units using heating and cooling water systems, process water systems, and hot well/cold well. FlexAir also specializes in retrofitting existing systems, including converting existing units from one heating and cooling medium to another, fan rework, and more.
