Johnson Controls - Penn P170LB-1C Dual Pressure Control

The Johnson Controls P170LB‑1C Dual Pressure Control provides combined high‑ and low‑pressure regulation in a single SPST switch for commercial refrigeration and air‑conditioning systems. It responds directly to system pressure changes on both sides, offering single‑device compressor protection. Moreover, it works with most common refrigerants—including ammonia‑compatible models—for versatile field use.

Precise Pressure Ranges

This control features a low‑pressure range of 20 inHg to 100 PSIG and a high‑pressure range of 100 to 500 PSIG, accommodating a wide variety of HVAC/R applications. Furthermore, the low‑pressure differential is adjustable between 7 and 50 PSIG, while the high‑pressure differential is preset at 55 PSIG for consistent performance.

Durable, Professional Construction

Encased in a NEMA 1 steel enclosure, the P170LB‑1C withstands demanding commercial environments. Additionally, its electromechanical design ensures long‑term reliability with minimal maintenance requirements.

Easy Installation

A universal mounting bracket and 1/4″ male flare pressure connection simplify installation on existing lines. In addition, built‑in auto‑reset for both high and low pressure reduces service time and callbacks.

Competitive Value

SPLYPRO offers this OEM‑quality dual pressure control at a competitive price, undercutting major distributors like Zoro, Grainger, SupplyHouse, and Amazon. As a result, HVAC professionals can maintain low inventory costs without sacrificing performance.
