Direct Fired LiBr Absorption Chiller 

Product Overview
The Direct Fired Lithium Bromide Absorption Chiller (Heater) is a high-efficiency and energy-saving system powered by natural gas, coal gas, biogas, or fuel oil. It uses a lithium bromide aqueous solution as the working fluid, where lithium bromide acts as the absorbent and water as the refrigerant. The system mainly consists of a high-temperature generator (HTG), low-temperature generator (LTG), condenser, evaporator, absorber, high-temp heat exchanger, low-temp heat exchanger, auto purge device, burner, vacuum pump, and canned pumps.

Advantages

• Double-effect generator structure for higher efficiency
  The HTG/LTG dual-stage design makes full use of the heat source, ensuring higher COP, stable performance, and energy savings.
• Auto-purging & anti-crystallization system for safe operation
  Equipped with multiple ejectors for fast vacuuming, and an intelligent system that prevents crystallization through level-based dilution and heating.
• Eco-friendly and low emissions
  Uses non-toxic, heavy-metal-free Li₂MoO₄ corrosion inhibitor; optional low-NOx burner with emissions ≤ 30 mg/Nm³ meets stringent environmental regulations.
• Smart control & easy maintenance
  Supports frequency control and load-adaptive operation; core components are modular and easy to clean or replace, reducing maintenance costs.
• Long service life, low operating cost
  Built with corrosion-resistant stainless steel and hydrophilic heat exchange tubes; designed service life ≥ 25 years for stable and economical long-term use.

Applications

• Commercial Buildings: Hotels, office buildings, hospitals, shopping malls
• Industrial Facilities: Petrochemical, paper, textile, metallurgy industries with recoverable waste heat
• District Energy Stations: Integrated cooling/heating energy centers
• Cascade Energy Utilization: Efficient use of natural gas, biogas, waste heat
• Hot Water or Process Cooling Demands: Food, pharmaceutical, electronics industries
