Penn refrigeration and temperature controls are the workhorse mechanical controls of the commercial refrigeration industry. Now part of the Johnson Controls portfolio, the Penn brand traces back to the 1930s and remains widely specified for pressure switching, temperature control, flow proving, and modulating water valve service across commercial refrigeration, air conditioning, and process cooling applications.
TCI Supply stocks the current Penn priced catalog and maintains an extensive quote-only inventory covering discontinued and legacy Penn models. Whether you are servicing a walk-in cooler pressure switch, a chiller high-limit temperature control, or a condenser water regulating valve, we can source the right Penn part fast.
Penn refrigeration and HVAC controls provide critical electromechanical protection, fan cycling safety, and temperature regulation across industrial cooling networks and boiler plants. Because these rugged systems require exact alignment of pressure trip limits, capillary lengths, valve modulations, and electrical contact configurations, sourcing an identical legacy part code is essential to maintain equipment safeties. Contact our dedicated mechanical sourcing team today to locate your specific Penn pressure cutout, flow switch, temperature bulb, or regulating valve.
We maintain a comprehensive warehouse inventory of current production and legacy discontinued Penn components. This allows mechanical contractors and facility engineers to repair heavy equipment in-place without triggering extensive system redesigns.
Single-pole and dual-pole pressure switches containing adjustable cut-in and cut-out setpoints. Engineered for compressor safety cutout, lube oil failure detection, high/low pressure limits, and fan cycling across vacuum options up to 500+ PSI.
Premium bulb-and-capillary temperature switches utilized for thermal safety cutouts, fan staging, and defrost timing loops. The A19 remote bulb configurations are the global industry standard for walk-in cooler and freezer applications.
Liquid and air flow proving switches built with flexible paddle designs. Critical for interlocking circuits on industrial chillers, steam boilers, and cooling tower loop networks.
Direct-acting, temperature-actuated modulating water valves. The V46 opens on rising temperature for cooling loops, while the V47 closes on rising temperature for heating applications. Widely used for condenser water regulation and process cooling.
Ultra-durable replacement capillary hoses featuring synthetic braiding, designed specifically for Penn P-series remote pressure-sensing and gauge configurations.
Penn equipment designations follow a position-specific alphanumeric structure that separates internal switch actions, pressure thresholds, and adjustment scale styles. Review the standard decoding blocks below.

Buying Tip on P70 Pressure Control Replacement: The P70 series contains a large array of highly specific variants (P70AA, P70CA, P70DA, etc.) differentiated closely by operational pressure range, electrical contact switching action, and the layout of the adjustment scale. Never order by the baseline model code alone; the two-letter suffix determines physical configuration and terminal integration fit. If your existing nameplate is heavily worn or obscured, e-mail a clear image of your hardware assembly to our technical team to identify the exact OEM replacement path.
Maintaining dependable refrigeration safety circuits and modulating water lines demands an accurate understanding of brand history, switch ranges, and sensor sizing. Review our technical answers below.
