In order to operate air-conditioning units and heating and ventilation systems quietly, the sealing and insulation specialist HANNO (Laatzen) develops and produces high-quality, high-performance and reliable sound and thermal insulating materials. At the ISH, the company now presented individual solutions with a focus on the growth market of heat pumps. "We are pleased about the strong response at the trade fair - we recognise a high demand for insulation", summarises Markus Fehrmann, Sales Manager at HANNO.

Hanno-Tect-F-free: Hydrophobic and fluorine free

The open-cell melamine foam Hanno-Tect-F-free is the first water-repellent impregnated Hanno product that does not contain PFAS and is therefore more environmentally friendly. The hydrophobically adjusted foam absorbs sound effectively and, at only ten kilograms per cubic metre, is a real lightweight. Hanno-Tect-F-free has a low 导热系数 (λ < 0.035 W/mK) and also scores points for its very good fire behaviour (HL2 according to EN 45545).

Hanno-Protecto pf: 系统噪声控制

Hanno-Protecto pf is a sound and vibration absorbing material for enclosure and capsule surfaces in refrigeration, air-conditioning and ventilation technology, among others. The bitumen-impregnated wool felt boards and foils have a stabilising, stiffening and weight-increasing effect on all metals and plastics. This absorbs or prevents structure-borne sound, which therefore does not become airborne sound.

Hanno-Fiber: Versatile all-rounder for sound insulation and isolation

The polyester fleece Hanno-Fiber is suitable for 吸音隔热 in refrigeration, air-conditioning and ventilation systems. The all-round product is available in both hydro- and oleophobic versions.
