Corinte ACCS E/W

Product catalog summary

Product Overview

The Corinte air curtain is engineered for premium entrances requiring elegant design and low noise. Available in two models (ADCS and ACCS), it supports both horizontal and vertical mounting. Constructed from stainless steel with polished, mirror-polished, or brushed finishes, it features black intake and outlet grilles (RAL 9005). The unit incorporates Thermozone technology for optimized airflow and is controlled via the SIRe system, which offers Basic, Competent, and Advanced control levels.

Specifications

Mounting: Horizontal (recommended height 3 m) and Vertical (recommended width 5 m with two units flanking the opening).
Dimensions: Lengths vary by model and orientation (e.g., ACCS horizontal: 1–3 m; vertical: 2–3 m).
Heating Options: Ambient (no heat), Electrical (ADCS: 15–22.5 kW; ACCS: 8–23 kW), Water heating with high (WH) or low temperature (WL) coils.
Airflow & Velocity: Velocity ranges from ~3.0 m/s to 11.0 m/s depending on model and mounting.
Compliance: CE certified, IP20 protection class.

Technical Data

Detailed specs include output power, airflow rates, temperature rise, sound levels, voltage, amperage, and weight per model. For example, the ACCS25E20 electrical heating model delivers 6.6–19.8 kW output, airflow between 2340–4500 m³/h, and noise levels of 48–65 dB(A). Water heating models specify supply/return temperatures, flow rates, pressure drops, and outlet air temperatures for both high and low temperature coils.

Installation and Mounting

Horizontal: Mounted near doors with air grille facing down; connections on left or right. Electrically heated units require minimum 1800 mm outlet-to-floor clearance. Installation options include wall, ceiling, or hanging with supplied brackets.
Vertical: Installed vertically near doors, typically two units for symmetry. Connections can be top or bottom. Units rest on adjustable feet and must be secured at the top.

Connections and Controls

Integrated SIRe PC board manages control with modular connectors for external devices. Electrical connections differ by mounting and heating type, with separate power/control supplies for electrical heating. Water connections use DN20 (horizontal) or DN25 (vertical) inside thread fittings. Valve kits manage water flow and are compatible with SIRe control levels.

Valve Kits and Water Control

VOS: On/off two-way valves with shut-off.
VOSP: Pressure-independent on/off valves ensuring constant flow.
VMO: Modulating valves with stepless actuator control.
VMOP: Pressure-independent modulating valves combining constant flow and modulation.
VOT & VMT: Three-way valves with on/off or modulating actuators.

Valve kits come in DN15, DN20, DN25 sizes with specified Kv values and max flow rates at 10 kPa pressure drop.

Accessories

ACCW: Wall brackets for horizontal mounting in various stainless steel finishes.
ACCSEH: Extension hood for vertical mounting to fill ceiling gaps (height adjustable 100–1000 mm).
AXP300: Floor collision protection to prevent damage.
FH1025: Flexible hose (DN25, 1" inside thread) for pipe connections.

Performance and Output Charts

Water-heated ACCS WH models include charts detailing airflow, heat output, return water temperature, water flow, pressure drop, and outlet air temperature at supply water temps of 110 °C and 90 °C with room temp at +18 °C. These assist in selecting appropriate models and settings.
