48 CES - Truck Mounted De-Icing Tank Sprayer

Questions & Answers

Questions:

1. Please confirm whether the required tank capacity is 4,000 L or 10,000 L. Do both entries refer to the same main tank, or are the multiple tanks required? Please state the required usable capacity and any minimum headspace allowance.

a. We request that the company physically inspect the vehicle to confirm compatibility. We request a single-tank deicing system with a minimum capacity of 4,000 liters (approximately 1,056 gallons), with the largest capacity possible within applicable vehicle weight limitations. To support current and future mission requirements, the tank must be capable of being filled by both top gravity loading and transfer pump. Total deicing machine weight must not exceed 14 short tons (28,000 pounds). Based on Konsin Eco deicer, the estimated weight per 1,000 liters is approximately 2,844 pounds.

Total vehicle height, with the tank installed, must not exceed 11 feet. The cargo bed floor begins at a height of 4 feet.

2. Please confirm whether the minimum spray coverage is 40 ft (12.192 m) or 10 m, and whether this means total treated swath or throw distance from each side.

Please reconcile the 8 ft maximum machine width with the 12 ft spray-system limit and identify the allowable transport and operating widths and spray-hardware arrangement.

a. We request that the company physically inspect the vehicle to confirm compatibility. The unit must provide a minimum liquid spray width of 10 meters and distribute deicing fluid evenly across that width. The deicing liquid must be applied through a spray system and not by means of a long spray bar. The spray bar or spray unit must not exceed the width of the truck, which is 2.5 meters (approximately 8 feet). The spray hardware may extend from the rear of the truck, as the tailgate will be removed during operation.

The truck bed interior dimensions are 14 feet in length and 7 feet in width at the side walls; however, due to the bed support design, the bottom 6 inches narrows to 6 feet 4 inches in width.

3. Please identify the deicing chemical(s), concentration, specific gravity, minimum ambient/fluid temperature, required application-rate range, and operating-speed range. What coverage uniformity and wind/test conditions govern acceptance? Are in-cab controls, section shutoff, or automatic ground-speed compensation required?

a. We request that the company physically inspect the vehicle to confirm compatibility. Konsin Eco De-Ice and Anti-Ice Fluid, manufactured by CHELA Intelligent Cleaning Company, uses potassium acetate as its active ingredient. The fluid has a specific gravity of 1.29, equivalent to approximately 10.76 lb/gal, a pH range of 10.4–10.8, conductivity of 91 mS, and viscosity of 25–30 mPa·s; the test temperature and measurement basis for conductivity and viscosity should be confirmed. The minimum fluid temperature is −37 °C, and the compatible applicator operating-speed range is 20–30 mph. Application rates range from 0.25 to 1.5 gallons per 1,000 square feet and must be dynamically managed through computerized chemical-metering systems to maintain the required application rate as vehicle speed changes.

4. Please provide the receiving truck make/model, usable internal bed dimensions, tailgate/access restrictions, payload and axle limits, and approved attachment points, with drawings or photos if available. Is the 10 ft height measured from the skid base or from ground level when installed? Does the 15-ton limit mean U.S.

short tons, metric tonnes, or U.K. long tons, and does it include the complete filled sprayer, fuel, and accessories?

a. We request that the company physically inspect the vehicle to confirm compatibility. The primary trucks will be Kenworth(T880 & T370 2 example models) with model years ranging from 2018 - 2023 but all trucks have the same 15 short ton weight capacity. The truck bed interior dimensions are 14 feet in length and 7 feet in width at the side walls; however, due to the bed support design, the bottom 6 inches narrows to 6 feet 4 inches in width.with the tank installed, must not exceed 11 feet. The cargo bed floor begins at a height of 4 feet. Total deicing machine weight must not exceed 15 short tons while filled (30,000 pounds). Based on Konsin Eco deicer, the estimated weight per 1,000 liters is approximately 2,844 pounds.Tailgates are removed while deicer is installed and gate latches can be used to help secure unit in truck. total deicher machine weight with everything including fluid cannot exceed 14 short tons

5. Please clarify whether the painted-steel/corrosion-resistant material requirement applies to the chassis, the wetted tank, or both. Are baffled polyethylene and stainless-steel tanks acceptable? Please identify any mandatory tank construction, baffling, fill connection, drainage, or flushing requirements.

a. Painted steel or corrosion resistant material applies for all equipment parts of the chassis. Tanks need to be baffled and should be made of High-density polyethylene (HDPE) or cross-linked polyethylene (XLPE) or Stainless steel.

Tank need to be top filled via gravity and needs capability to connect transfer pump. The tank also need to be able to be drain via gravity or transfer pump.

machine will need to be flushed with clean water before storage.

6. Please define the required "jacking drawbar storage leg kit" for this dump-truck-mounted skid and describe the intended loading/removal method. Must lifting eyes, forklift channels, and storage legs support a filled unit or an empty unit only? Please provide any required fork-pocket dimensions, lifting configuration, and storage-leg height.

a. The machine must be capable of installation and removal by forklift or crane.

It must also be capable of being securely fastened within the dump truck, ideally using eyelets that may also serve as lifting points for a crane. The machine will only be installed, removed, and stored while empty. Forklift access points must accommodate tine openings of 4 inches by 6 inches and a tine length of 10 feet. The unit must include slots for two forklift tines spaced 4 feet apart. Storage legs must elevate the machine sufficiently to prevent ground contact, with a minimum ground clearance of 2 feet."
