Introduction The Energy ducted units have been designed to allow energy savings in the ventilation systems of public and private environments, such as bars,

The heat exchange between the discharged air and the fresh air introduced occurs via a static cross-flow exchanger, designed to recover over 50% of the heat.

3 Introduction The Energy ducted units have been designed to allow energy savings in the ventilation systems of public and private environments, such as bars, restaurants, offices, shops, etc., by recovering the heat from the air discharged and transferring it to the fresh air introduced into the environment. The heat exchange between the discharged air and the fresh air introduced occurs via a static cross-flow exchanger, designed to recover over 50% of the heat. The Energy range features 6 sizes suitable for horizontal installation (1 to 6) and 5 for vertical installation (2 to 6), covering a range of air flows from 400 to 3500 m³/h. 3

4 Constructional characteristics SUPPORT FRAE The structure of the unit is made of galvanised plate sandwich panels, 24 mm thick, filled with high-density polyurethane foam. Size ENY 1, on the other hand, uses both sandwich panels and self-supporting panels insulated with foam material. The side panels are easily removable, allowing the position of the air inlet and outlet to be modified, even on site. Sizes ENY 2-6 are provided with blind openings. During installation, it is possible to select the position of the openings. Once the position is selected, open them, by means of hacksaw, operating on the pre-cut slots located on the panels. HEAT RECOVERY The heat recovery are static plate exchangers that transfer heat between two flows of air due to the temperature difference. Being static, there are no moving parts. This is a guarantee of very high reliability and operating safety. The two flows of hot and cold air entering the heat recovery unit are sub-divided into sections that run between two plates, which carry hot air and cold air alternatively. These sections are sealed to prevent any possible contamination between the air flows. The heat is exchanged by the plates that make up the walls of the sections, with efficiency that reaches values between 50% and 75%. To increase the efficiency of the exchanger, the surfaces of the plates are fitted with special swirlers. Condensate collection pan Condensate collection pan with drain connection on the side (external diameter 14 mm). Fan assembly The discharge and intake air fans are double intake with forward blades. The rotor is directly coupled to the electric motor, reducing the overall size. Single-phase motor, 230V power supply with built-in motor protection, three speeds on all models. Air filters Pleated cell filters, 48mm thick, efficiency G3, with filtering media made from regenerable synthetic material, class F1. The filters can be removed from below after having removed the bottom panel of the unit. Post-heating coil (optional) Built on a special galvanised plate frame, expanded 3/8 copper pipes, aluminium fins with 2.1 mm fin spacing, brass manifolds. Electric post-heating coil (optional) Electric heating coil made of armoured elements, in aluminium extrusion with wide exchange surface, contained inside a galvanized plate frame easily mountable on the fresh air flow between heat recovery unit and fan. The electric coil is provided with double safety thermostat: one with automatic preset and one with manual reset. 4

The kit provides special filter frames: frame for 98mm filter in micro-pleated fibreglass, filtering efficiency F6 frame for flat pre-filter G1, thickness 10mm. The use of the F6 filter implies, taking into account the same air flow of the machine, a reduction of the available pressure of about 25%.

26 Diagram of fresh air intake in BY-PASS In very cold times, it is often necessary to fit a system to defrost the exchanger. By closing DAR S1 and opening DAR S2, the heat recovery unit is bypassed by the fresh air, allowing the air discharged from the environment to defrost the heat recovery unit. IPORTANT: the dampers are not supplied by SABIANA. odels ENY 2-6 are provided with blind openings. During installation, it is possible to select the position of the openings. Once the position is selected, open them, by means of hacksaw, operating on the pre-cut slots located on the panels. Legend R = fresh air from the outside E = discharge air from the inside S1 = damper 1 S2 = damper 2 RB = fresh air intake in by-pass 26
