Drick DRK-C20 Industrial Compressor-Based Dehumidifier

Overview

The Drick DRK-C20 is a heavy-duty, compressor-based industrial dehumidifier engineered for continuous, high-capacity moisture removal in controlled environments where ambient humidity poses risks to product integrity, process stability, or storage safety. Unlike desiccant or thermoelectric systems, the DRK-C20 employs refrigerant-cycle condensation—drawing ambient air across a chilled evaporator coil maintained below the dew point, causing water vapor to condense and drain into an integrated collection reservoir. The now-dry air passes over the warm condenser coil for sensible reheating before discharge, minimizing net cooling load while maintaining stable room temperature. This thermodynamic cycle ensures consistent performance across ambient temperatures ranging from 5 °C to 35 °C and relative humidity levels between 40 %RH and 95 %RH—making it suitable for year-round operation in unconditioned industrial spaces such as raw material warehouses, pharmaceutical packaging halls, electronics assembly cleanrooms (non-classified zones), and food-grade storage facilities.

Key Features

• Robust refrigeration architecture featuring a high-efficiency rotary compressor, copper-aluminum finned evaporator and condenser, and optimized airflow design—enabling sustained 12 kg/h dehumidification output under ISO 8502-3 test conditions.
• Intelligent digital control panel with dual-sensor readout (ambient temperature and RH), programmable setpoint control (10–98 %RH), real-time fault diagnostics (e.g., sensor drift, compressor overload, high-temperature shutdown), and auto-restart after power interruption.
• IP21-rated electrical enclosure ensuring protection against solid objects >12.5 mm and vertically dripping water—meeting basic industrial environmental requirements per IEC 60529.
• Structural durability: powder-coated steel chassis, reinforced base frame, and four swivel casters with locking brakes—designed for repeated repositioning in large-floor-plan facilities without structural compromise.
• Energy-conscious operation: optimized refrigerant charge and fan-motor matching deliver a specific power consumption of ≤333 W·L⁻¹·h⁻¹ at rated capacity, aligning with ISO 16813 energy-efficiency benchmarks for industrial dehumidifiers.

Sample Compatibility & Compliance

The DRK-C20 is not intended for direct sample processing but serves as an environmental conditioning system supporting GxP-aligned operations. It maintains stable humidity setpoints critical for ASTM D4332 (conditioning of test specimens), ISO 291 (standard atmospheres for conditioning and testing), and USP (packaging requirements for pharmaceuticals). Its non-corrosive internal airflow path (stainless steel drain pan, epoxy-coated coils) prevents particulate shedding or metal ion leaching—ensuring compatibility with sensitive materials including hygroscopic APIs, printed circuit boards, archival documents, leather goods, and dried agricultural products. While not certified to UL 1995 or CE EN 60335-2-40 out-of-the-box, its electrical design conforms to IEC 61000-6-2/6-4 EMC immunity/emission standards, and documentation supports internal validation protocols required under FDA 21 CFR Part 11 Annex 11 and EU GMP Annex 15.

Software & Data Management

The DRK-C20 operates via embedded firmware without external PC dependency; however, its RS-485 Modbus RTU interface (optional add-on module) enables integration into facility-wide Building Management Systems (BMS) or SCADA platforms. Logged data—including runtime hours, cumulative condensate volume, average RH deviation from setpoint, and fault event timestamps—can be exported via USB or serial protocol for audit trail generation. All parameter changes are time-stamped and user-identifiable when linked to a central authentication server, satisfying ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) for GLP/GMP-regulated environments.

Applications

• Pharmaceutical manufacturing: humidity control in tablet coating rooms, lyophilizer loading areas, and secondary packaging suites to prevent caking, adhesion, or microbial proliferation on excipients.
• Electronics production: suppression of electrostatic discharge (ESD) risk and solder paste oxidation in SMT staging zones and PCB storage cabinets.
• Food processing: stabilization of ambient RH during drying, curing, and ambient storage of jerky, fruit leather, smoked fish, and baked confectionery to inhibit mold growth and texture degradation.
• Cultural heritage preservation: climate buffering in museum storage vaults housing parchment, textiles, and wooden artifacts susceptible to hydrolytic degradation.
• Industrial logistics: moisture mitigation in bonded warehouses storing corrugated packaging, raw timber, leather hides, and tobacco bales prior to further processing.

FAQ

What is the minimum ambient temperature at which the DRK-C20 maintains rated dehumidification capacity?
Rated performance (12 kg/h) is validated at 30 °C / 80 %RH per ISO 8502-3. Below 15 °C, capacity declines progressively due to reduced vapor pressure differential; automatic defrost cycling activates below 8 °C to prevent evaporator icing.
Can the unit operate continuously without manual water drainage?
Yes—the integrated 12 L condensate tank includes float-switch auto-shutoff, and optional continuous drain hose connection (Ø16 mm) supports uninterrupted 24/7 operation when gravity-fed to floor drain.
Is remote monitoring supported natively?
No native Ethernet or Wi-Fi; however, the RS-485 port permits third-party protocol translation to BACnet/IP or MQTT via gateway hardware for centralized dashboard integration.
Does the DRK-C20 comply with RoHS or REACH substance restrictions?
All PCBAs, refrigerant (R-410A), and housing materials conform to EU RoHS Directive 2011/65/EU and REACH SVHC candidate list thresholds as verified by supplier declarations and material safety data sheets (MSDS).
What maintenance intervals are recommended for long-term reliability?
Biannual inspection of air filter, coil cleanliness, refrigerant line integrity, and electrical terminations; annual calibration of RH sensor traceable to NIST-certified reference hygrometers.
