Services: BAS, EMS & Automation Solutions
Cold Temp Solutions installs, programs, commissions, and services building automation and refrigeration control systems for industrial and commercial facilities across the San Francisco Bay Area and Northern California. The company’s controls technicians hold field experience across multiple major platforms — including Emerson E2 and Einstein, Copeland CoreSense, Danfoss AK-SM 800 and SM880, Sporlan Micro-Thermo, Allen-Bradley ControlLogix and CompactLogix (Rockwell Automation), and Tridium Niagara Framework AX and N4 — enabling platform-appropriate solutions for facilities ranging from single-rack cold storage operations to large multi-zone ammonia and CO₂ transcritical systems requiring enterprise-level building management system (BMS) integration. Controls work performed by Cold Temp Solutions includes new system commissioning and setpoint configuration, retrofit and upgrade of obsolete control panels, graphical HMI and touchscreen display programming, alarm management and notification setup, and remote monitoring connectivity via Ethernet/IP, BACnet/IP, Modbus TCP, and LonWorks network protocols.
Cold Temp Solutions designs and implements refrigeration control and energy management system (EMS) integrations that consolidate compressor rack controllers, evaporator controllers, condenser fan VFDs, lighting controls, and HVAC units into a single supervisory platform for centralized monitoring, alarming, and data logging. Tridium Niagara N4 is the preferred platform for multi-system BMS integration projects requiring open-protocol interoperability across mixed-manufacturer equipment — Niagara’s vendor-neutral architecture supports simultaneous BACnet, Modbus, SNMP, and legacy proprietary driver connections within a single supervisor. For food retail and cold storage applications, Emerson E2 and Danfoss AK-SM 800 provide purpose-built refrigeration supervisory control with native case controller and rack controller integration, demand defrost scheduling, floating suction and head pressure optimization, and HACCP temperature logging functions that satisfy FDA Food Safety Modernization Act (FSMA) recordkeeping requirements. Remote monitoring and alarming — including 24/7 temperature and system fault notification via text, email, and dashboard — reduces emergency response time and supports facilities operating without on-site refrigeration technicians around the clock.
Cold Temp Solutions performs controls upgrades on refrigeration systems originally installed with obsolete or discontinued controllers — including legacy Hussmann Protocol, Heatcraft AAON, old Danfoss AKC series, and first-generation Emerson Retail Solutions platforms — replacing end-of-life hardware with current-generation controllers that support modern network protocols, remote access, and energy optimization algorithms. For industrial ammonia facilities, the company programs and services Allen-Bradley ControlLogix and CompactLogix PLCs used in custom-engineered machine control and safety interlock systems, including integration with IIAR-compliant emergency refrigerant stop (ERS) circuits and high-pressure emergency relief logic. Controls and BAS automation services are available to food storage and distribution, pharmaceutical manufacturing, post-harvest and controlled atmosphere storage, winery, and commercial building operations throughout Contra Costa, Alameda, Solano, Sacramento, Napa, Sonoma, and San Joaquin counties. To discuss a controls assessment, new installation, or legacy system upgrade at your Northern California facility, contact Cold Temp Solutions at (925) 374-4014 or inquiry@coldtemps.com.
