NAVI+ Selective collectors

Shell type

The automated robotic assembly line, designed with advanced single-frame engineering, combines high performance, durability, and perfect sealing. It comes with a 10-year warranty.

One-piece casing featuring anti-corrosion technology, ensuring complete sealing against moisture and airborne particulates.

40mm-thick rock wool insulation with a density of 50 kg/m³.

Hydraulic circuit (manifold and riser pipes) made entirely of copper.

Full-surface, selective “harp-type” (grid) absorber, laser-welded to ensure exceptionally high efficiency, even under the most challenging weather conditions.

Shatterproof, translucent, prismatic safety glass with low iron oxide content for enhanced solar absorption.

Boiler

GLASS

Inner water tank: 2.5 mm thick.

Constructed from two deep-drawn shells joined by a SINGLE ROBOTIC WELD (halved).

Closed-circuit jacket: 1.8 mm thick cold-rolled steel for maximum long-term durability.
Antimicrobial HARD ENAMEL A2+ coating: fired at 870°C (glass-lined). A specialized formula for deep-drawn tanks, certified by WRAS and NSF, ensuring truly hygienic water.

Thermal insulation: 50 mm thick, dense, eco-friendly polyurethane to retain hot water.

Enhanced cathodic protection: utilizes a magnesium anode with double the length and thickness.

Heat exchanger: (metal coil) included in triple-energy models, allowing for operation with a boiler or heat pump.

Innovative new design: outer casing featuring exceptional aesthetics.

Type Dimensions
1 120 Lt 52 cm x 105 cm
2 160 Lt 52 cm x 130 cm
3 200 Lt 58 cm x 130 cm
4 300 Lt 58 cm x 180 cm

INOX

Outer casing of the water heater: grey-painted steel (RAL 9006) or non-magnetic stainless steel (AISI 304 BA), 0.5 mm thick.

Inner water tank: stainless steel (AISI 316L), 2.0 mm thick.

Closed-circuit jacket: stainless steel (AISI 316L), 1.2 mm thick.

Thermal insulation: dense, eco-friendly polyurethane, 50 mm thick.

Cathodic protection: via a long-length magnesium anode.

Electric heating element: equipped with an adjustable safety thermostat.

Heat exchanger: (stainless steel coil) in “triple-energy” models, allowing for operation with a boiler or heat pump.

Innovative new design: outer casing featuring an exceptionally aesthetic appearance.
