Core products and their applications are as follows:
1. Pressure Controllers (Including P/PC Series)
Suitable for managing pressure in two main types of HVAC systems, with core applications:
• Commercial: Fitted for building and commercial complex units. They monitor high and low pressure, safely starting/stopping equipment to stabilize pressure and enhance energy efficiency.
• Industrial: Designed for high-temperature plant conditions. They protect compressors, reliably operate under full load, and ensure dependable actuation.
2. Differential Pressure Controllers (Including FSD Series)
Designed for monitoring oil pressure and water circuit differential pressure, suitable for both scenarios:
• Commercial: Stabilize differential pressure and flow in water systems, improving the heat exchange efficiency of central air conditioning.
• Industrial: The FSD series monitors oil pressure, featuring a low-pressure delay shutdown function to prevent equipment wear.
3. Flow Switches
Applied in water circulation and refrigerant circulation systems, with different scenarios:
• Commercial: Monitor water circulation in central air conditioning systems. They send signals upon detecting anomalies to prevent main unit failure.
• Industrial: Monitor refrigerant and lubricant oil flow to prevent equipment damage caused by insufficient flow.
4. Solenoid Valves (SV, NSV Series)
Control refrigerant on/off, adapted for two operational conditions:
• Commercial: SV series (diaphragm type) offers good waterproofing, vibration resistance, and compatibility with various refrigerants.
• Industrial: NSV series (piston type) features long service life, zero pressure differential opening capability, and suitability for high-load operations.
5. Condensing Pressure Regulating Valves & Temperature/Water Flow Regulating Valves
Regulate system pressure and temperature, meeting two primary needs:
• Commercial: Regulate condensing pressure, water temperature, and flow to assist in energy conservation.
• Industrial: Resist high temperatures and corrosion, stabilize pressure, and adapt to high-temperature plant environments.
6. Thermostatic Expansion Valves & Liquid Injection Valves
Core refrigeration components, designed for differentiated needs: they provide precise temperature control in commercial systems; in industrial settings, they adapt to high temperatures, regulate flow, improve energy efficiency, and prevent overloads.
