Product overview
Direct-fired lithium bromide absorption chiller/heater is a large-capacity industrial unit for cooling or heating. It uses gas (natural gas, town gas, LPG) or oil (diesel) as the primary driving energy with only limited electricity as auxiliary power, lithium bromide solution as the absorbent and water as the refrigerant. The system is designed to lower electrical consumption and to smooth peak-valley load differences, making it suitable for regions with abundant gas resources and for facilities seeking fuel-driven HVAC solutions.

Types

• H2 direct-fired chiller/heater (COP: 1.34)
• H3 direct-fired chiller/heater (COP: 1.25)
• J type direct-fired chiller/heater (COP: 1.42)

Function
Provides chilled water above 0°C and hot water up to 95°C. Applicable to comfort cooling/heating and a variety of industrial process heating/cooling requirements.

Capacity Range
233–11,630 kW (20–1000×10^4 kcal/h) or 186–9,280 kW (16–800×10^4 kcal/h). Configurable for single- or multi-unit installations.
