Delmar and Dewalt® Release Complete Handbook on Construction Estimating
Delmar announced the release of the Dewalt® Construction Estimating Complete Handbook for building and construction professionals.
The Dewalt® Construction Estimating Complete Handbook, a comprehensive but concise guide covering all aspects of the construction estimating process, is useful for both experienced professionals who want to polish their estimating skills as well as for junior estimators, assistant project managers, and students studying construction management. This guide covers key industry profit-making factors including bid planning, scope review, quantity take-off for all trades and divisions, cost analysis, value engineering, Excel spreadsheet estimating tutorials and much more. The handbook is also ideal for general contractors or construction managers who need to have knowledge of every trade involved on a jobsite.
Traceable® Humidity/Temperature/Dew Point Meter
Control Company's Traceable® Digital Hygrometer/Thermometer/Dew Point instrument provides a response time of under 10 seconds with a resolution of 0.01%RH, 0.01°F/°C, and 0.01° dew point °F/°C. It samples one-and-a-half times per second. “Fuzzy logic” algorithm pinpoints the exact answer almost instantly. The direct-reading instrument has an accuracy of ±1.5%RH and ±0.4C. Results are reported in both degrees F and degrees C from -40.00 to 220.0F (-40.00 to 104.0C) temperature, and from -40.00 to 140.0F (-40.00 to 60.00C) dew point.
To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

DC-Powered, Ductless Mini-Split Air Conditioner Unveiled by Solar Panels Plus
Solar Panels Plus (SPP), has released the SplitCool DC18, DC-powered, high SEER air conditioning system. The SplitCool DC18 is ideal for any commercial or residential location where cooling or heating is required and grid power is unavailable, unreliable or requires generators.
The SplitCool runs off a battery bank that is supplied power from an array of photovoltaic panels and installs without ducts, eliminating the majority of installation and materials costs. The unit can be added quickly to an existing structure and eliminates nearly 30% of cooling or heating losses, which occur in the ductwork of forced air systems. It allows each room to be conditioned as a separate zone. The SplitCool DC18 can be used in permanent and temporary remote buildings or structures, such as construction office trailers, portable classrooms or medical facilities.
Taco Introduces the Solar X-Pump Block®
Taco's Solar X-Pump block combines a variable speed solar differential temperature control, bronze heat source and heat sink circulators, and a stainless steel flat plate heat exchanger into one compact package. The variable speed controls are designed to match solar collector output, a feature that increases system performance by 20%, sources say. With just four pipe connections, the installation is complete.
The Solar SXPB can be set up to maintain a temperature differential between the solar collector(s) and up to two primary and optional auxiliary storage tanks. The unit can support a booster pump as part of a drain-back system, comes with a heat dump option and freeze protection. The Solar X-Pump block's large LCD screen conveniently displays the amount of thermal energy harvested by the collector. The system also comes with three strap-on sensors.
