Panasonic S-250PE4E Big PACi 25.0kW High Static Pressure Hide-Away Ducted Indoor Unit – R32
Hurry up, only 10 items left in stock.
The Panasonic S-250PE4E is a 25.0kW Big PACi high static pressure hide-away duct unit for larger commercial spaces – retail floors, restaurants, halls and open-plan offices served by a ducted distribution system.
The renewed Big PACi indoor unit is 16kg lighter than conventional 10HP models and has a split-able design that makes piping in narrow ceiling voids far easier. It offers a cost-effective route for small to mid-sized projects and can also be integrated with Panasonic VRF systems or the PACi water heat exchanger.
Panasonic Cloud control compatibility and 0-10V demand control give building managers flexible energy management, with CONEX/IoT controls and an optional commercial Wi-Fi adaptor.

Good to know
This is a split-system component that contains or connects to R32 refrigerant, so it must be installed and commissioned by an F-Gas registered engineer. It is supplied as a single unit – pair it with a compatible Panasonic outdoor/indoor unit to make a complete system. Ductwork and wired controller are sold separately.

Specifications
Compact and lightweight design
With a low weight of just 21 kg, this ventilation unit can be installed quickly and safely by a single installer. Its space-saving footprint makes the DucoBox Energy Comfort perfectly suited for small plant rooms and confined technical areas.
Software-controlled left/right configuration
The unit is designed for maximum installation flexibility. Left- or right-hand airflow orientation is adjusted entirely via software, eliminating the need for mechanical modifications. This is made possible by an innovative patented double bypass system.
Automatic calibration
Using constant pressure calibration technology, the AUTO calibration function reduces commissioning time by up to 50%. In real-world installations, this can translate into lower labour costs and faster system setup.
High energy efficiency
Advanced dynamic air filtration ensures consistently high heat recovery efficiency. When combined with optional intelligent demand control based on CO₂ and humidity sensors, the system delivers excellent indoor air quality while minimising energy consumption.
Smart copy function for fast commissioning
An integrated software-level copy feature allows installers to duplicate settings and parameters from one unit to another. This is especially valuable for multi-unit or repeated housing projects, ensuring consistent performance and significantly reducing setup time.
