Heavy-duty Series

Modular ductless purifier for heavy wok and fry cooking.

Heavy-duty Series

Overview

The Heavy-duty Series (KL-D-ND12 to ND24) targets heavy Chinese wok cooking, fry stations and community canteens. Its four-stage system – water-cycle filtration, high-voltage ESP, polymer mesh and deodorization – reliably treats dense smoke. The all-stainless body is modular: upper and lower sections split for easy installation (just four expansion bolts when ceiling-hung) and tool-free disassembly for cleaning. A built-in water tank (36 L on the 1.6 m model) has a level sensor that blocks startup when empty, plus inlet, drain and overflow ports for safety. Mature and widely deployed, the lower section is fully washable for low day-to-day maintenance.

Key Features

  • Four-stage: water-cycle + ESP + polymer + deodorization
  • All-stainless modular body, split for easy install
  • Built-in 36 L water tank with level sensor
  • Inlet, drain and overflow ports for safety
  • Lower section fully washable, low maintenance

Application Scenarios

  • Chinese Wok Kitchens: Built for the intense smoke and grease of high-heat wok cooking — the water-cycle stage captures heavy particulate before it reaches the ESP.
  • Community & Factory Canteens: Handles 500+ meals per shift with continuous-duty design, modular body, and washable lower section for low daily maintenance.
  • Hotel Banquet Kitchens: Reliable 24/7 performance for hotel main kitchens that prepare banquets, buffets, and room service simultaneously.
  • Chinese Restaurant Chains: Engineered for the steam, oil, and high-volume output of Sichuan, Cantonese, and Hunan cuisine restaurants with heavy wok usage.
  • Central Kitchens: Deployable in centralized meal-prep facilities where consistent purification across multiple cooking lines is mandatory for compliance.
