What temperature should the hot water be for an auto-wash ESP system?

The optimal hot water temperature for an auto-wash commercial kitchen ESP (Electrostatic Precipitator) system ranges from 40°C to 60°C (104°F–140°F). This standard temperature range balances efficient grease removal, stable equipment operation,and long-term durability of core components.

Commercial kitchen fume consists of polymerized oil grease that hardens and adheres tightly to ESP aluminum collector plates.Cold water cannot dissolve solidified grease effectively, leading to incomplete cleaning, increased wind resistance, and reduced purification efficiency.Warm hot water within the standard range efficiently softens oil deposits,enhances the activity of special grease detergent,and thoroughly flushes residual grease from electrode plates and internal gaps.

Temperature control is critical to avoid equipment damage.Water temperature below 40°C results in poor degreasing performance, failing to remove heavy kitchen grease and causing gradual blockage of the ESP system.In contrast, water temperature exceeding 65°C poses major risks: it easily deforms thin aluminum electrode plates, damages insulating materials,and weakens the precision of the electrostatic electric field,ultimately affecting fume purification effectiveness.

For daily maintenance,the auto-wash system defaults to a stable 50°C optimal temperature,suitable for most catering scenarios with light to medium grease pollution.For heavy grease environments such as hot pot and barbecue kitchens,adjusting the temperature to 55–60°C achieves a deeper cleaning effect.

In short, maintaining hot water between 40–60°C ensures thorough grease cleaning,protects core ESP components,and keeps the auto-wash system running stably with consistent long-term purification performance.
