Large Capacity Refrigerant Filling Equipment Heat Pump Production 0.5-10kg Charging Range High Precision

Large Capacity Refrigerant Filling Equipment Heat Pump Production 0.5-10kg Charging Range High Precision

Product Overview

HongCe Large Capacity Refrigerant Filling Equipment is designed for production lines that charge large refrigeration systems such as heat pumps, commercial air conditioners, chillers, and large refrigeration units. With a single charging range of 0.5-10kg, high-precision load cell weighing, and integrated vacuum evacuation, the machine delivers repeatable large-charge filling for modern heat pump and HVAC manufacturing.

Product Introduction

Heat pump production presents a different charging challenge from small refrigeration systems: the charge quantity is measured in kilograms rather than grams, and accuracy at this scale directly affects system efficiency, heating capacity, and seasonal performance ratings.

The HongCe Large Capacity Refrigerant Filling Equipment combines a high-resolution load cell weighing system with a controlled charging valve train to deliver charges from 0.5kg to 10kg with accuracy of ±1g within 1kg and ±0.5% above 1kg. Vacuum evacuation is integrated into the charging sequence, and the control system supports MES connectivity and production data storage for complete process traceability.

Main Features

• Large Charging Range: 0.5-10kg single charge capacity for heat pumps, large AC units, and refrigeration systems.
• High Precision Weighing: Industrial load cell with 0.1g resolution and charging accuracy of ±1g within 1kg; ±0.5% above 1kg.
• Integrated Vacuum Evacuation: 8 L/s vacuum pump with equipment vacuum level of <2 Pa.
• Multi-Refrigerant Support: R134a, R410A, R32, R407C and R1233zd with refrigerant-specific charging programs.
• Production Data Management: 12-inch touch screen HMI, MES connectivity, 3-year data storage, RJ45/RS-485 interfaces.
• High Charging Speed: Fast charging valve train with flow control for large charges, maintaining throughput on heat pump lines.

International Reference Standards

• ISO 5149 - Refrigerating systems and heat pumps: safety and environmental requirements
• ISO 817:2024 - Refrigerants: designation and safety classification
• EN 378 - Refrigerating systems and heat pumps: safety and environmental requirements
• GB/T 18430 - Water chilling (heat pump) packages using the vapor compression cycle

Technical Specifications

Core Technology Behind the Equipment

• High-Resolution Weighing: Industrial load cell and anti-vibration mounting deliver stable readings during active charging.
• Flow-Controlled Charging Valve Train: Fast-fill and fine-fill stages optimize both speed and accuracy for kilogram-scale charges.
• Vacuum + Charge Sequence: Automated evacuation before charging reduces moisture and non-condensable gas in the system.
• Process Traceability: Charge records with timestamps, operator, and product serial data support quality audits and warranty analysis.

Frequently Asked Questions

What is the maximum charge this machine can handle?
The standard configuration supports single charges from 0.5kg to 10kg. Larger ranges can be configured for chiller and industrial refrigeration applications.

How accurate is charging at the 10kg scale?
Accuracy is ±0.5% above 1kg, which for a 10kg charge means within approximately ±50g, supported by the 0.1g resolution weighing system.

Can this equipment be integrated into a heat pump production line?
Yes. MES connectivity, barcode interface, and communication with upstream and downstream stations allow the machine to operate as part of an automated production line.
