PTK 2026

Proxll will be attending PTK 2026 with a focus on one critical issue for Norwegian hydropower:
Safe and reliable operation of water gates and trash racks, even under challenging winter conditions.

Typical challenges include:

• Frozen or slow-moving water gates
• Ice and snow accumulation on trash racks and screens
• Reduced water flow and increased head loss
• Need for manual intervention under challenging conditions
• Increased risk of production losses and HSE incidents

When the waterway does not function as intended, availability, safety and operational costs are directly affected.

Water gates play a critical role in regulating the water flow to the turbine. Reliable and predictable gate movement is essential for safe operation and optimal power generation.

Ved ising og lave temperaturer kan vannluker:

• freeze in place or move unevenly
• be subjected to increased mechanical loads, potentially resulting in costly repairs
• reduce control over power generation

Unpredictable operation of water gates can quickly lead to operational disruptions and, in the worst case, a complete shutdown of power generation.

Trash racks installed at water intakes are designed to maintain a steady water flow and prevent debris from entering the system. When ice, snow and frazil ice accumulate on the trash racks, the effective intake area is reduced, which can result in:

• Reduced water flow
• Increased load on the system
• More frequent need for cleaning
• Manual intervention in exposed areas

Effective frost and ice protection solutions are therefore essential for both operational reliability and safe working conditions.

Why Choose Proxll’s Heating Solutions?

Proxll delivers effective heating systems designed to prevent ice and frost build-up on exposed areas of hydropower facilities, including water gates, guide walls, gates, trash racks and other critical surfaces. By maintaining a stable temperature above freezing, we help ensure reliable operation, even under challenging winter conditions.

Reduced Risk and Lower Costs

Ice and frost can lead to unplanned downtime, increased maintenance requirements, and additional stress on the equipment. With the right heating solution, the risk of operational disruptions and damage can be reduced, resulting in more predictable operation and lower overall lifecycle costs.
