Vertical PP balcony-terrace inlet body DN50/75/110 with bitumen flange HL310KH

Functional properties and technical characteristics

The HL310KH drain body is a high-quality component of the drainage system, designed specifically for balconies, terraces, and floors in residential and commercial buildings. Made of durable polypropylene (PP) with a factory-welded bituminous collar, it represents an ideal solution for insulation systems based on bituminous material.

Construction and materials ensuring long-term functionality

The drain body is made of durable polypropylene (PP), which is characterized by high resistance to weathering and dimensional stability across a wide range of temperatures. This material is resistant to chemical and biological corrosion, guaranteeing many years of trouble-free operation in outdoor conditions.

A key structural element is the factory-welded bituminous collar, which ensures a perfect connection with bituminous insulation. Such integration eliminates the risk of thermal bridges and leaks at the contact point between the drain and the waterproofing. The collar is designed to allow for easy and secure sealing of the entire system.

Hydraulic parameters and installation compatibility

The device offers universal connection compatibility thanks to three available nominal diameters: DN50, DN75, and DN110. This flexibility allows for adaptation to various types of sewage installations and design requirements.

Hydraulic capacity has been precisely defined for each diameter:

• DN50: 1.65 l/s - ensures effective water drainage during heavy rainfall
• DN75/DN110: 1.25 l/s - guarantees stable system operation at higher flows

A compact installation height of 144 mm facilitates installation in limited structural spaces while maintaining full hydraulic functionality.

Practical application and operational advantages

The HL310KH drain body performs excellently in drainage systems for terraces above heated rooms, loggia balconies, and wet rooms in public utility buildings. Its design enables effective drainage of rainwater and meltwater, while simultaneously protecting the building structure from moisture.

An additional advantage is the practical protective cover included in the package, which protects the drain from mechanical damage and contamination during transport and installation. This system is compatible with a wide range of installation accessories from HL Hutterer & Lechner.

The product meets the requirements of European standards for wastewater drainage devices (EN 1253), confirming its high quality of workmanship and safety of use.
