Condensate Drain Pan and Line

Product Specifications

Technical details and manufacturing context for Condensate Drain Pan and Line

Definition

The condensate drain pan and line is an essential part of dehumidification systems, responsible for capturing moisture condensed from the air during the dehumidification process and safely draining it away from the equipment to prevent water accumulation, corrosion, and microbial growth that could damage the system or compromise air quality. This component consists of a pan positioned beneath the cooling coils and a drain line that conveys the collected water to an appropriate disposal point. The pan is typically fabricated from galvanized steel, stainless steel, PVC, or ABS plastic, with material selection based on the operating environment and required corrosion resistance. For corrosive environments, stainless steel grades 304 to 316 (per ASTM A240) are specified. Pan thickness ranges from 0.8 to 1.5 mm, and dimensions vary from 300 to 1200 mm in length and width, with custom sizes available. The drain line, with a diameter of 15 to 50 mm (per ISO 6708), is made from PVC to PP (per ASTM D1785), depending on temperature requirements. The system operates within a temperature range of 5 to 60°C and a pressure range of 0 to 0.4 MPa, with a leakage rate of zero. Corrosion resistance is verified by a minimum of 500 hours of salt spray testing (per ASTM B117). The weight of the assembly ranges from 2 to 15 kg, and connection types include threaded or barbed fittings from G1/2 to G2 (per ISO 228). Drainage capacity is matched to the dehumidifier output, typically 10 to 50 L/h. Proper installation and maintenance are critical to ensure reliable operation and prevent blockages or leaks. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

As air passes through the dehumidification system's cooling coils, moisture condenses on the cold surfaces. The condensate drain pan collects this water through gravity flow, then the drain line channels it away via gravity or pump-assisted drainage to an appropriate disposal point, maintaining dry conditions within the equipment. The pan is sloped to facilitate water flow, and the drain line must be properly sized and installed to prevent backflow and ensure efficient removal. Regular inspection and cleaning are necessary to prevent clogging and microbial growth.
