The casing of an Air Handling Unit is far more than just a box — it is the first line of defence against heat gain, condensation, vibration, and noise. At Airmake Cooling Systems Pvt. Ltd., we manufacture high-quality AHU PUF panels (Polyurethane Foam insulated panels) that provide the structural integrity, thermal performance, and hygienic interior surfaces that modern HVAC systems demand. Based in Noida, we supply AHU PUF panels to HVAC contractors, AHU manufacturers, pharmaceutical companies, food processing plants, and commercial building contractors across Delhi NCR and throughout India.
Our PUF panels are pressure-injected with CFC-free polyurethane foam at a density of 40 kg/m³ — delivering a rigid, closed-cell insulation core that resists thermal bridging, moisture ingress, and structural deformation across a long service life. Whether you need standard panels for a commercial AHU casing, stainless steel inner-skin panels for a pharmaceutical clean room, or custom-dimensioned panels for a specially designed unit, Airmake Cooling has the manufacturing capability to deliver them accurately and on time.
A PUF panel (Polyurethane Foam panel) is a sandwich-construction insulated panel consisting of two metal skins with a rigid polyurethane foam core injected between them under pressure. In the context of Air Handling Units, these panels form the walls, roof, floor, and doors of the AHU casing — replacing older fibreglass or rock wool insulation methods with a far superior, self-supporting, and hermetically sealed construction.
The closed-cell PUF core provides exceptional thermal resistance (low U-value), virtually eliminating heat gain from outside or condensation on interior surfaces — both of which would otherwise compromise the energy efficiency and hygienic integrity of the AHU. The metal skins (GI, pre-coated, or stainless steel) provide structural strength, corrosion resistance, and — in the case of SS inner skins — easy-to-clean, bacteria-resistant surfaces for pharmaceutical and food processing applications.
All components of the AHU — fan section, filter section, cooling and heating coils, dampers, and access doors — are installed inside the PUF panel casing, which is mounted on a rigid base or chassis. The result is a compact, well-insulated, low-maintenance AHU that performs consistently throughout its service life.

Airmake PUF panels are versatile and are used across multiple applications wherever high-quality thermal insulation and structural integrity are required:
When you source AHU PUF panels from Airmake Cooling, you are working with a manufacturer who understands the critical role these panels play in the overall performance of your AHU system. We do not simply cut and assemble panels — we engineer them to meet the thermal, structural, hygienic, and dimensional requirements of your specific project. Our manufacturing process uses precision tooling and quality-controlled PUF injection to ensure consistent foam density, uniform panel thickness, and airtight edge sealing on every panel we produce.
As an MSME and Udyam-certified manufacturer based in Noida, we offer competitive pricing with the reliability of a direct manufacturer — no middlemen, no compromise on quality. Our team provides full technical support from panel specification through to delivery, and we can accommodate custom sizes, unusual skin material combinations, and special thickness requirements for non-standard projects.
An AHU PUF panel is a sandwich-construction insulated panel used to build the casing of an Air Handling Unit. It consists of two metal skins (pre-coated steel or SS) with a rigid CFC-free polyurethane foam core pressure-injected between them. This construction provides superior thermal insulation, structural rigidity, low weight, and — with SS inner skins — hygienic surfaces for pharmaceutical and food processing AHUs.
Standard panels are available in lengths up to 2400mm, widths up to 1200mm, and thicknesses from 25mm to 50mm. The PUF core density is 40 kg/m³. Custom sizes outside these ranges are available on request for non-standard AHU designs.
The outer skin is available in pre-coated steel or stainless steel (SS). The inner skin is available in plain galvanized iron (GI) or stainless steel (SS). The SS inner skin is specified for hygienic applications such as pharmaceutical AHUs, food processing units, and hospital HVAC systems where the interior surface must be easy to clean and bacteria-resistant.
Yes. All Airmake AHU PUF panels use CFC-free polyurethane foam, making them environmentally responsible and fully compliant with current environmental regulations. The closed-cell foam structure also naturally resists moisture and prevents condensation formation within the panel.
AHU PUF panels are used in pharmaceutical manufacturing, food and beverage processing, clean rooms, hospitals, commercial HVAC buildings, data centres, and industrial facilities — anywhere that requires thermally efficient, structurally robust, and hygienic AHU casing construction.
We manufacture AHU PUF panels at our Noida facility and deliver across Delhi NCR and throughout India. We provide custom specifications, competitive direct-manufacturer pricing, on-time delivery, and full technical support for every order.
Whether you are building a standard commercial AHU, a pharmaceutical-grade clean room unit, or a specially designed system for a demanding industrial application, Airmake Cooling can supply the right PUF panels — in the right dimensions, with the right skin materials — delivered on time and at a competitive price.
