DM34-DM200
DMZL
Scroll compressors use meshing fixed/moving scrolls to compress refrigerant, offering quieter operation (<55dB), higher efficiency (15% better than reciprocating units), and fewer moving parts (reducing maintenance) than traditional compressors. The Scroll Compressor MBP 2-12HP DMZL (DM34-DM200 series) is optimized for small-scale cooling (2-12 HP), making it ideal for commercial and light industrial applications.
Countertop drink displays and snack coolers need compact, quiet compressors. The DM34-DM200 series’ small footprint (242x242x415mm) fits under counters, while its <55dB operation avoids disturbing customers. Its energy efficiency also cuts electricity costs by $200/year per unit vs. reciprocating compressors.
Offices, cafes, and retail stores (50-500 sq. ft.) need 1-5 ton AC systems. The DM34-DM200 series’ axial/radial flexible scrolls handle voltage fluctuations (common in urban areas), preventing sudden shutdowns. Its lightweight design (26-56kg) also simplifies installation on rooftops or walls.
Pharmacies and labs use small refrigerators (50-200L) to store insulin, antibiotics, and samples at 2-8°C. The DM34-DM200 series maintains ±0.5°C precision, avoiding medication spoilage. Its hermetic design also prevents contamination (critical for ISO 13485-compliant facilities).
The fixed and moving scrolls can adjust radially (up to 0.5mm) and axially (up to 0.3mm) to:
• Accommodate small debris (prevents compressor damage).
• Handle liquid refrigerant (avoids slugging, a top issue with reciprocating units).
• Maintain tight sealing (≤0.1% annual leak rate), complying with environmental standards.
• Moving Scrolls: PTFE-coated aluminum alloy (reduces friction by 30% vs. uncoated scrolls).
• Bearings: Porous bronze (self-lubricating, eliminating the need for frequent oil changes).
• Casing: Lightweight aluminum alloy (26-56kg) with a powder-coated finish, resistant to humidity in cafes or labs.
Traditional scroll compressors draw high starting current (up to 150A), tripping circuit breakers in weak grids. The DM34-DM200 series uses unloading startup to reduce starting current by 40% (e.g., 22A vs. 37A for a 2HP model), ensuring reliable operation in urban or rural areas.
• Piping Connections: Soldering or flaring/roto lock (optional) for easy installation.
• Power Supply: 220V/1ph/50Hz (for small units: DM34HE/DM50HE); 380-420V/3ph/50Hz (for larger units: DM70HE-DM200HE).
• Crankcase Heater: 70W (prevents oil stratification in cold environments).
• Refrigerant Compatibility: R404A/R507A, R22 (optimized for MBP applications).
Our team provides 3D drawings to help you integrate the DM34-DM200 series into compact spaces (e.g., under-counter displays, small AC units). We also recommend optimal placement to maximize airflow and cooling efficiency.
For local technicians, we supply installation kits with:
• Pre-wired power cords (to avoid wiring mistakes).
• Piping adapters (for soldering/flaring).
• Step-by-step manuals with photos and videos.
This reduces installation time by 50% and labor costs by $300/unit.
• Warranty: 12 months on all components; 18 months if you use our recommended oil (POE 32).
• Troubleshooting: Free online resources include FAQs, video tutorials, and a troubleshooting flowchart for common issues (e.g., startup failures, noise).
We stock critical parts (scrolls, bearings, fuses) in regional warehouses (USA, Europe, Asia). Most parts are delivered within 1-3 business days, and we offer free technical support to help you replace parts on-site.
