HVAC drip pan

-- Steady & Reliable Manufacturer --

Brief Product Description

The HVAC drip pan is a core product line for Cixi Chenfeng Electric, built for the space under evaporator coils and air handling equipment where condensate needs to be caught and channeled away before it can drip onto ceilings, floors or equipment below. As a sheet metal parts factory focused on central air conditioning accessories, we form drip pans in galvanized steel, stainless steel and aluminum, sized and shaped to match the coil footprint and cabinet dimensions our customers specify.

Each drip pan is stamped or formed from a single sheet where possible to minimize seam points, then welded or folded at the corners and sealed to hold water without leaking under normal operating conditions. We finish the pans with a corrosion-resistant coating or passivation layer so they hold up to years of condensation cycling without rusting through, which is the most common failure mode we see in cheaper stamped pans from other suppliers.

We supply HVAC drip pans both as standard stock sizes for common air handler models and as custom parts built to a customer's drawing or sample, including drain outlet position, pan depth and mounting tab layout. For OEMs building air handling units, we can integrate the drip pan into a broader parts package alongside brackets, panels and other sheet metal components, simplifying sourcing to a single supplier relationship rather than managing several vendors for one assembly.

Product Overview

A drip pan's job looks simple on paper, catch water, but the details that determine whether it performs well over years of service are all in the fabrication. Pan depth and slope toward the drain outlet need to be right so water does not pool and stagnate, and the seams and corner joints need to be genuinely watertight rather than just visually sealed, since a slow leak inside a ceiling void or mechanical closet can go unnoticed for a long time and cause real damage.

At Cixi Chenfeng, we form HVAC drip pans using CNC press brakes and stamping presses that hold consistent bend angles and corner geometry across a production run, then weld or crimp seams depending on the design and material. Stainless steel pans are typically TIG welded at the seams for a fully sealed joint, while galvanized pans may use a folded and sealed corner construction that is more cost-effective for high-volume standard sizes. Either way, every pan is checked for dimensional accuracy and, for larger or custom orders, leak-tested before it leaves the factory.

We work with HVAC equipment manufacturers, air handling unit builders and HVAC parts distributors who need a reliable supply of drip pans either matched to their own equipment designs or as generic replacement stock for field service. For OEM customers, we can develop tooling around a specific coil and cabinet design so the pan is a precise fit rather than a generic approximation, which reduces installation labor and callback risk on the customer's side.

Material selection generally comes down to the environment and budget: galvanized steel offers good corrosion resistance at a lower cost for indoor, conditioned-space installations, while stainless steel is the more durable choice where humidity exposure is higher or where a longer service life is the priority. We can advise on the right combination of material, gauge and finish once we understand the installation environment and expected duty cycle.

Application

HVAC drip pans are installed beneath evaporator coils in air handling units, fan coil units and ductless indoor units to collect condensate produced during cooling operation and route it to a drain line. They are used across residential air handlers, light commercial rooftop and split systems, and larger central plant air handling equipment.

When specifying a drip pan, the key details are the footprint of the coil section it sits under, the available depth in the cabinet, the position and size of the drain outlet, and whether the installation requires a secondary or auxiliary pan for overflow protection as a separate component. Installers should confirm the pan sits level with a slight slope toward the drain outlet, and that the drain connection is properly sealed, since even a well-made pan will leak at a poorly fitted outlet connection.

Advantages

Cixi Chenfeng builds drip pans with sealed, welded seams rather than relying on sealant alone, which holds up better over repeated wet/dry cycling than adhesive-sealed joints common in lower-cost imports. Our in-house tooling lets us match a specific coil and cabinet geometry rather than forcing a customer to adapt their design to a generic pan size.

Because drip pans are part of our core product range rather than a side item, we keep dedicated tooling and material stock for common sizes, which supports faster turnaround on repeat orders and more predictable pricing for customers running an ongoing HVAC parts program with us.

Frequently Asked Questions

Q: What materials are HVAC drip pans available in?
A: Galvanized steel, 201 or 304 stainless steel, and aluminum are all standard options, chosen based on the corrosion resistance and budget the application calls for.

Q: Can you build a drip pan to match our existing coil footprint?
A: Yes, send us a drawing or a sample pan and we will match the dimensions, drain outlet position and mounting details.

Q: Are the pan corners welded or just folded?
A: It depends on material and design: stainless steel pans are typically TIG welded at the seams, while galvanized pans may use a folded and sealed corner construction for standard sizes.

Q: Do you leak-test drip pans before shipment?
A: Leak testing is available for custom and stainless steel production orders, and we can add it as a standard step for any ongoing supply program on request.

Q: What drain outlet fittings can you accommodate?
A: We can position and size the outlet to match your specified fitting or connector, based on your drawing or sample part.

Q: Is stainless steel necessary, or is galvanized steel enough?
A: Galvanized steel performs well in typical indoor, conditioned-space installations; stainless steel is recommended where humidity exposure is higher or a longer service life is the priority.

Q: Can you supply drip pans as part of a larger parts package?
A: Yes, we regularly supply drip pans alongside brackets, panels and other sheet metal components for air handling unit builds.

Q: What is the lead time for a custom drip pan order?
A: Standard sizes ship faster since tooling already exists; custom sizes require tooling and sample approval first, which adds development time to the first order.
