Product catalog summary
Technical Documentation Overview
This document provides comprehensive specifications and benefits of various solar technology products, including flat-plate collectors, vacuum tube collectors, swimming pool absorbers, control units, and freestanding cylinders. It also includes installation guidelines and accessory options.
Flat-Plate Collectors
Three types of high-performance flat-plate collectors are detailed: TopSon F3-1, TopSon F3-Q, and CFK-1. Key specifications include dimensions, optical efficiency, heat loss coefficients, and maximum operating pressure. These collectors are certified to EN 12975 and Solar-Keymark standards, ensuring high energy utilization and environmental excellence. They feature weather-resistant aluminum housing, Rockwool insulation, and safety glass.
Vacuum Tube Collectors
The CRK vacuum tube collectors are noted for their high performance, durability, and modular design, suitable for both DHW heating and central heating backup. They maintain a vacuum for high thermal insulation and meet environmental standards.
Swimming Pool Absorbers
These absorbers provide an economical solution for heating swimming pool water, featuring low investment and operating costs, robust construction, and high energy yields. They are UV and weather-resistant with compact dimensions.
Control Units
Various control units like the BM-Solar programming module and solar modules SM1 and SM2 are described, which regulate solar circuits and optimize energy savings. These units feature eBus interfaces and are equipped with sensors for efficient operation.
Freestanding Cylinders
The SEM-1 and SEM-2 cylinders are designed for solar heating systems, featuring high-grade insulation and enamel-coated coils for efficient heat exchange. They offer a 5-year warranty and are optimized for temperature stratification.
Accessories
A range of accessories is available, including pump/fitting assemblies, solar expansion vessels, and pre-cooling vessels, designed to enhance the functionality and efficiency of solar systems.
Technical Information
Guidelines are provided for determining the required cylinder size based on factors like roof orientation, inclination, and climate zone. It also includes a calculation example for determining the number of collectors needed for a specific solar DHW coverage rate.
Specifications
  • DHW Demand: Approximately 75 liters per person per day for a household of 4 occupants.
  • Collector Types: Includes F3-1, F3-Q, CFK-1, and CRK, each with specific pressure drop ranges and installation configurations.
  • System Sizing: Recommendations vary based on the number of collectors and the type of collector used. Pipe diameters are specified for different collector configurations.
Procedures and Recommendations
  • System Sizing: Based on maximum line lengths and head of Wolf solar pump assemblies. Recommendations are provided for different collector types and numbers.
  • Installation Accessories: Various kits and accessories are available for rooftop and roof integration installations, including AluPlus and AluFlex-U kits for different collector orientations and roof pitches.
  • Control Units: Solar modules SM1 and SM2 are available for regulating solar circuits, with programming modules for standalone operation.
Standards and Testing
  • Collectors are tested to EN 12975 standards, ensuring weather and temperature resistance, and hail-proof construction.
Key Data from Tables
  • Collector Array Pressure Drop: Varies by collector type and number, e.g., F3-1 ranges from 65-150 mbar depending on the number of collectors.
  • Pipe Diameter Recommendations: Specific diameters are recommended based on the number of collectors and collector type, ensuring optimal flow and system efficiency.
Additional Features
  • Swimming Pool Absorbers: Made from UV and weather-resistant plastic for high energy utilization.
  • Solar Heating Expansion Vessels: Proper sizing and installation are crucial, with recommendations to use appropriate sizing programs.
