Import Energy Calculator (Hec2000-A / Hec2000-D) — Buy in Bulk from Supplier in South Korea (Republic Of Korea)

The HEC2000-A and HEC2000-D are dual-channel energy calculators designed for precise thermal energy measurement in heating and cooling systems, using paired temperature sensors and flow meters to compute energy in kWh or MJ. The HEC2000-A supports analog input from external flow meters, while the HEC2000-D includes built-in ultrasonic flow sensing. Both units feature a backlit LCD display with multi-language support and store up to 12 months of historical data in non-volatile memory. The device operates on 24V DC and is mounted on DIN rails for industrial control panels.

The instrument uses Class A platinum resistance thermometers for temperature measurement, with a resolution of 0.01°C and a range of -30°C to 120°C. Flow measurement for the HEC2000-D is based on transit-time ultrasonic technology with a typical accuracy of ±1% of flow rate. The housing is rated IP65 and designed for ambient temperatures up to 60°C. It does not include wireless connectivity or cloud integration; data export is limited to USB or RS-485 Modbus RTU. This aligns with the design philosophy of industrial-grade, offline-capable thermal meters.

This model is commonly purchased by facility managers in commercial buildings, hospitals, and district energy networks that require detailed energy accounting for billing or sustainability reporting. It is not intended for laboratory use or high-precision R&D. Units are shipped in anti-static ESD-safe boxes with protective caps on sensor ports. Trade terms are FOB Seoul or CIF port of destination, with a standard lead time of 5 to 7 weeks. MOQ is one unit, but bulk orders receive volume pricing upon request.

Korea 21 Flowmeter is a Seoul-based entity registered in Mapo-Gu with no public website, no factory photos, and no disclosed manufacturing capacity. Its trust tier is harbor, indicating only basic business registration verification. There is no record of response to buyer inquiries, and no certifications are listed or claimed. The supplier does not state whether it manufactures, assembles, or resells the HEC2000 series. No information is provided on warranty, repair centers, or technical support structure.

Buyers should assume this is a trading company with limited technical oversight. The product listing does not indicate whether calibration is performed in-house or outsourced. No details on component sourcing, firmware version, or quality control procedures are available. Due to the absence of response history and verification signals, buyers must independently validate all technical claims before procurement.
