Product Description

I. Positioning

The BSA645 series is HIGHLY's A-series line of fully hermetic rotary (rolling piston) compressors, covering three models: BSA645DT, BSA645CV, and BSA645CN, all with a uniform displacement of 6.45 cc/rev. This series uses eco-friendly R134a refrigerant and features compact structure, small size, light weight, and high energy efficiency. Widely applied in dehumidifiers, clothes dryers, cabinet air conditioners, and constant temperature & humidity equipment.

Note: BSA645DT-R1EN uses 230V/50-60Hz, R134a, 860W cooling, COP 2.21. BSA645CV-R1EN uses 220-240V/50Hz, 692W cooling, COP 2.35. BSA645CN-R1EN uses 208-230V/60Hz, 848W cooling, COP 2.31.

III. Detailed Overview

Feature: The BSA645 series adopts a fully hermetic rotary (rolling piston) structure, with the motor and rotor sealed in a single housing—extremely simple construction with minimal parts. The rotor and vane cooperate to complete suction, compression, and discharge, ensuring smooth operation with low vibration. All three models use R134a (ODP=0), compliant with environmental regulations. Factory-precharged with L22E or NEO 32 refrigerant oil for direct installation. Equipped with an accumulator (outer diameter φ31.8 mm, height 132 mm) to effectively prevent liquid slugging.

Advantage:

Three power specs precisely cover global markets. BSA645DT-R1EN fits 230V/50-60Hz wide-frequency; BSA645CV-R1EN fits 220-240V/50Hz; BSA645CN-R1EN fits 208-230V/60Hz. All share identical 6.45 cc/rev displacement but differ in capacity and efficiency tuning—BSA645CV-R1EN leads in COP at 2.35 W/W; BSA645DT-R1EN delivers maximum cooling at 860 W; BSA645CN-R1EN offers balanced 848 W at COP 2.31 under 60Hz.
Ultra-lightweight design. BSA645CV-R1EN weighs only 4.7 kg. Compact dimensions (height ~169 mm, OD ~φ92-94 mm) provide significant installation advantages in space-constrained dehumidifiers and cabinet A/C units.

Benefit: For dehumidifier OEMs, the 860W/692W/848W capacity range precisely matches 5–30L dehumidifier requirements. Three power variants cover China, North America, and Europe—one platform serves global export needs, drastically simplifying product line management and inventory costs. For dryer and cabinet A/C manufacturers, R134a and compact lightweight design reduce system integration difficulty and shipping costs. Compared to reciprocating compressors: 40% less installation space, 25% weight reduction, 60% fewer reciprocating parts, lower power consumption, and higher COP.

IV. Application Scenario Quick-Selection Guide

Application Scenario	Recommended Model	Power Supply	Key Advantage
5-30L Dehumidifier (China/Europe)	BSA645CV-R1EN	220-240V/50Hz	692W, COP 2.35 (highest)
5-30L Dehumidifier (North America/60Hz)	BSA645CN-R1EN	208-230V/60Hz	848W, COP 2.31
Dehumidifier/Dryer (Wide-frequency export)	BSA645DT-R1EN	230V/50-60Hz	860W, max cooling
Cabinet Air Conditioner	BSA645DT-R1EN	230V/50-60Hz	860W, compact & lightweight
Constant Temp & Humidity Equipment	BSA645DT-R1EN	230V/50-60Hz	Stable cooling, high reliability

Selection Tip: For China/Europe 50Hz → BSA645CV-R1EN (highest COP); for North America 60Hz → BSA645CN-R1EN (848W balanced); for max capacity or wide-frequency export → BSA645DT-R1EN (860W).

V. Frequently Asked Questions (FAQ)

Q1: What are the core differences among BSA645DT, BSA645CV, and BSA645CN?

All share 6.45 cc/rev displacement. The difference lies in power supply and performance tuning: BSA645DT-R1EN (230V/50-60Hz, 860W max); BSA645CV-R1EN (220-240V/50Hz, COP 2.35 highest); BSA645CN-R1EN (208-230V/60Hz, 848W, COP 2.31).

Q2: What refrigerant and oil do BSA645DT-R1EN use?

R134a eco-friendly refrigerant, factory-precharged with L22E or NEO 32 oil. R134a systems MUST use POE ester oil—do NOT mix with mineral oil.

Q3: What applications is the BSA645 series suitable for?

Primarily 5–30L dehumidifiers, also clothes dryers, cabinet air conditioners, and constant temperature & humidity equipment.
