HVAC drain pan

Product Overview

Condensate management is one of the least visible yet most important functions in an HVAC system. When a drain pan fails, the result is water damage to ceilings, insulation and finished interiors, which quickly becomes a service problem for the equipment brand and a cost problem for the building owner. Cixi Chenfeng Electric manufactures HVAC drain pans as part of its central air conditioning accessories range, focusing on leak resistance, corrosion protection and fit with the equipment they serve.

Pan Types and Sizes

• Primary drain pans beneath fan coil coils and air handling sections
• Secondary or auxiliary pans for safety and overflow protection
• Vertical and horizontal orientation pans with matching outlet positions
• Custom-shaped pans that follow coil and casing layouts

Materials for Different Conditions

Galvanized steel is the standard choice for most commercial projects because it balances cost and corrosion resistance. Stainless steel 304 or 316 is available for high-humidity or hygienic environments, such as hospitals, laboratories and food-related spaces where long service life is a priority. Where required, pans can be finished with coatings or wrapped with insulation to reduce sweating on the exterior surface.

Forming and Welding for Leak Resistance

A drain pan lives or dies by its seams. We form deep-drawn or bent pans with welded or sealed corners, checking flatness and slope so that water moves toward the outlet without pooling. Drain fittings, threaded couplings or pipe stubs can be welded in the position your design requires, and flanges are shaped to seat properly against coils and casings. For stainless steel pans, welds are cleaned and passivated to restore corrosion resistance.

Design Details Buyers Ask About

• Slope angle and depth to suit airflow and coil height
• Outlet type, size and location, including side or bottom outlets
• Edge height and flange design for coil seating
• Provision for insulation attachment or pre-installed insulation lining
• Mounting holes and support tabs for secure installation

Testing and Delivery

Pans can be checked for leaks with water testing at agreed sampling levels, and dimensions are verified against the approved sample. Packing includes protective film and separators to prevent scratches on stainless steel, with cartons or pallets marked by part number.

Reducing Risk for Equipment Brands

Water leakage claims are expensive, and a drain pan is often the first part investigated when they occur. Reducing that risk starts with a good design, including generous slope, adequate depth and well-placed outlets, and continues with consistent manufacturing. We share design observations from previous projects, such as avoiding sharp internal corners where debris collects, and we can adjust flange shapes so that pans seat firmly against coils. Documented inspection results and agreed leak testing levels give your quality team clear evidence that each batch meets the approved standard.

Installation practices also affect performance, so we can supply simple guidance for your assembly or site teams, covering outlet connection, support spacing and insulation placement. Where projects use long pans that may flex under water weight, we add stiffening ribs or support tabs so the pan holds its slope over time. These small details keep condensate moving toward the drain throughout the life of the equipment.

When sourcing HVAC drain pans, provide drawings, material, quantity and outlet specifications. Our team will prepare a quotation and can advise on improvements that lower leakage risk and cost.
