Rialto Commercial Dehumidifiers

Why Rialto Businesses Need Purpose‑Built Dehumidification

In Rialto and the wider Inland Empire, temperature swings, seasonal humidity events, process moisture, and tightly sealed buildings can drive RH above safe ranges. The result: mold growth, corrosion, product damage, equipment downtime, and uncomfortable occupants. Properly sized commercial dehumidifiers stabilize RH, protect inventory and electronics, and support compliance with ASHRAE 62.1/55 and California Title 24—all while improving indoor air quality and reducing latent loads on your cooling systems.

Complete Commercial Dehumidification Solutions

We engineer and deliver systems that match your process, building, and budget:

Refrigerant (DX) dehumidifiers with hot‑gas reheat: Ideal for offices, retail, gyms, and IT rooms—precise RH control without over‑cooling spaces.
Desiccant dehumidifiers: High‑capacity moisture removal for industrial, food, pharmaceutical, and cold‑storage applications, even at low temperatures.
DOAS/ERV integration: Dedicated Outdoor Air Systems and Energy Recovery Ventilators condition ventilation air and manage latent loads before air reaches the space.
Smart controls and BMS: Networked sensors and RH setpoints, demand control, and fault alerts to optimize comfort and energy use.
Condensate and hygiene design: Correct drainage, filtration, and clean‑access points to prevent microbial growth and water damage.

A 4th‑Generation, Engineering‑Led Team

Our family of engineers has spent 80+ years solving complex HVAC challenges across Southern California. We are factory‑trained by leading manufacturers—Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea, Gree, and Haier (China)—to ensure proper selection, commissioning, and warranty‑compliant service. From large warehouses and logistics hubs to medical clinics and multi‑site retail, we specialize in big and complex projects where details matter.

Our Process: From Load to Long‑Term Reliability

1) Site assessment & goals: We document RH targets, product/process needs, ventilation rates, and code requirements specific to your Rialto facility.
2) Engineering & selection: Load calculations, psychrometric analysis, and equipment matching (desiccant vs. DX, DOAS, ERV, reheat) aligned with ASHRAE and Title 24.
3) Integration: Clean tie‑ins to existing rooftop units, split systems, or chilled water; attention to duct design, airflow balance, and electrical coordination.
4) Installation & commissioning: Manufacturer‑aligned start‑up, sensor calibration, controls programming, and performance verification at design conditions.
5) Maintenance & monitoring: Proactive plans that keep RH on target, reduce energy use, and extend equipment life, with clear reporting you can share with QA and compliance teams.

Code Compliance, IAQ, and Energy Performance

We design for compliance with ASHRAE 62.1/55/90.1 and California Title 24, balancing ventilation, latent removal, and sensible cooling. Where available, we identify utility incentives and control strategies that lower operating costs without sacrificing indoor air quality or product integrity. The result is tighter RH bands, fewer comfort complaints, and measurable ROI.

Service, Repair, and Preventive Care

Already have equipment? We troubleshoot, repair, and optimize most commercial dehumidifier makes and models. Our preventive maintenance includes coil and desiccant media inspections, drain and pump checks, calibration of RH sensors, filter service, and control sequence verification—keeping your system reliable through Rialto’s hottest months and seasonal humidity spikes.
