Envirostat FP4E: 4kW Simple Frost Protection Thermostat

Introducing the ENVIROSTAT FP4E & FP4i Electronic Thermostats—your ultimate solution for energy-efficient frost protection. Designed specifically for pipework where thermal insulation alone falls short, these advanced thermostats ensure your pipes remain protected from freezing and ice damage. Ideal for controlling heater tape or Infra-Red (IR) quartz lamps, the ENVIROSTAT FP4 series offers two robust models to suit your needs:

• FP4E: A straightforward, reliable thermostat offering 4kW frost protection with simple temperature control functions.
• FP4i: An enhanced version with additional alarm features for comprehensive protection and monitoring.

The Envirostat FP4E offers energy-efficient 4kW frost protection for pipework, heater tapes, and Infra-Red heating systems. Designed to perform where insulation alone is insufficient, it features a soft start function, built-in encapsulated 2m sensor, and IP65-rated protection for reliable use in demanding environments.

Its solid-state design ensures long-lasting, maintenance-free operation, while its high current capacity (20A) makes it suitable for heavy-duty frost protection applications. Available with selectable temperature ranges (-10°C to +10°C or 0°C to +20°C), the FP4E provides flexibility for diverse installations.

Choose the FP4E for straightforward frost protection, or the FP4i for added alarms and monitoring. Both models are trusted across industries to protect against frozen pipes, improve heating system efficiency, and support applications in the fight against Legionellaceae.
