重点介绍SECOP SC18CNX.2

The History of Secop: Over 70 Years of Innovation

Secop is widely recognized as one of the founding pioneers of modern hermetic compressor technology. Its legacy spans several decades, marked by pivotal rebrandings and technological milestones.

1. The Danfoss Era (1950s – 2010)

• 1951–1956 (The Beginnings): The company’s roots trace back to Danfoss Compressors, a division established by the Danish industrial group Danfoss. In 1956, production facilities and headquarters were officially founded in Flensburg, Germany, along with the launch of the iconic "PW" compressor, which revolutionized household refrigeration.

• 1972 (The Birth of the SC Platform): Danfoss introduced the SC compressor platform featuring PTC (Positive Temperature Coefficient) starting devices. This platform set an industry standard for light commercial refrigeration that is still highly relevant today.

• 1977–1990s (Mobile Cooling & Green Refrigerants): In 1977, the company introduced the "BD" series of battery-driven DC compressors, opening up the mobile cooling market (vehicles, boats, and RVs). In 1993, anticipating environmental regulations, Danfoss became an early leader in sustainability by launching compressors designed for R600a (isobutane). They hit the milestone of 150 million compressors produced by 1997.

2. Transition to Secop (2010 – Present)

• 2010 (The Birth of Secop): The private equity firm AURELIUS AG acquired the Danfoss Compressor division. The company was rebranded as Secop GmbH, maintaining its German engineering heritage but operating independently.

• Strategic Acquisitions & Global Footprint: In 2013, Secop acquired ACC Fürstenfeld in Austria to strengthen its European manufacturing base. Over the years, production consolidated across highly productive facilities in Zlaté Moravce, Slovakia, and Wuqing, China.

• Recent Ownership: After a brief period under the Nidec Corporation (2017–2019), Secop was acquired by the industrial private equity fund ESSVP IV (managed by Orlando Management AG) in late 2019, under which it continues to thrive as an independent, premium brand focusing on eco-friendly, green refrigerants and highly efficient medical and light commercial cooling.

Secop SC18CNX.2: Functions and Features

The Secop SC18CNX.2 (often cross-referenced under the active manufacturing code 104H8866) is a robust, fixed-speed hermetic reciprocating compressor belonging to the classic "SC" series.

Core Technical Functions

• Vapor Compression Cycle: As a reciprocating compressor, it uses a piston-and-cylinder mechanism driven by an internal motor to draw in low-pressure refrigerant gas, compress it to a high pressure/temperature, and pump it out to the condenser.

• Low Back Pressure (LBP) Optimization: The SC18CNX.2 is functionally optimized for LBP applications, meaning it operates efficiently when the evaporating temperature is very low, working smoothly within a range from -40°C up to -10°C (and stretch-tested for certain MBP ranges depending on configurations).

• Eco-Friendly R290 (Propane) Operation: This model is purpose-built to run on R290 hydrocarbon refrigerant, which features an extremely low Global Warming Potential (GWP). Its internal mechanics are fine-tuned to handle the unique thermodynamics and oil-solubility traits of propane.

• CSIR Motor Design: It utilizes a Capacitor Start / Induction Run (CSIR) motor configuration. The starting capacitor delivers high starting torque (HST), allowing the compressor to start reliably even under high differential pressures or fluctuating local voltages.

Technical Applications of the SC18CNX.2

Because of its high starting torque, robust SC-chassis design, and optimization for the energy-efficient R290 refrigerant, the SC18CNX.2 is widely deployed in commercial and heavy-duty settings:

1. Light Commercial Food Service Equipment

• Commercial Freezers & Storage Cabinets: Used in professional reach-in or walk-in storage freezers in restaurants, commercial kitchens, and supermarkets where deep-freezing performance must recover quickly after frequent door openings.

• Ice Cream Display Freezers: Ideal for commercial glass-top scoop freezers or chest freezers that demand continuous sub-zero temperatures to preserve ice cream texture.

2. Retail and Beverage Cooling

• Glass Door Bottle Coolers / Merchandisers: Often used in larger-capacity commercial beverage display fridges installed in convenience stores or supermarkets.

• Open-Air Display Cabinets: Powering multi-deck supermarket display cases that require heavy duty, stable cooling capacities.

3. Food Production & Automation

• Commercial Ice Makers: Found in modular ice-cube or flake-ice machines where high starting torque is required to push through the freeze-and-harvest cycles.

4. Cold Chain & Medical Cooling Solutions

• Biomedical & Laboratory Freezers: Increasingly utilized in laboratory environments for storing low-temperature medical samples, vaccines, and biological agents where exact thermal stability and premium mechanical reliability are non-negotiable.
