The most popular VAL6 radiant options have been the KBE5L-2 and the EPX models. The KBE5L-2 model has a slightly higher radiant capacity than the KBE5S (standard) model and has a 15 G fuel tank, which simplifies re-fill timing, such as every 12 hours. While the EPX model is rated a considerably stronger performer, the EPX model doesn’t consume much more fuel per hour than the KBE5L-2 model, but if maximizing grain drying is the deciding factor, you will get more performance from the EPX model. All three larger VAL6 diesel models are compatible with the EconoDri cabinet (as well as the LP & NG), and are designed to maximize humidity reduction and air-temp rise proportionate to the VAL6 model, while each model consumes approximately 1 G of diesel fuel or less per hour. While customers have told us about using the EconoDri/VAL6 combos on varying size bins, 5000B to 12,000B bins were the most common size reported with one combo per bin. Obviously with higher grain moisture, the variable in time to dry was directly proportionate to grain moisture. We have had producers telling us that they used EconoDri/VAL6 combos on larger capacity bins, and happy with the results, but this seemed to be consistent with less extreme grain-moisture levels. In the case of larger bins and / or higher grain moisture, we recommend capacity expansion with multiple EconoDri/VAL6 combos per bin fan (as pictured) to provide an increased volume of dry air. Just as 25% moisture grain in the field rarely naturally dries to 15% moisture in a week, the same allowance is reasonable for the EconoDri/VAL6 combo, though it needs to be pointed out that EconoDri/VAL6 combos typically continue to deliver dry air into grain when daily air conditions can turn humid and stop natural field drying. EconoDri/VAL6 Tooling Considerations— Again, if the producer’s goal is to have their shop space heater help with some grain drying, an EconoDri will help their VAL6 do this.  If the producers goal is to maximize the good that their aeration & storage bins can provide to to keep harvest moving, reduce damaging grain from other systems’ increased handling / moving, and ideally, reduce the cost of drying grain with an EconoDri/VAL6 combo, this is another harvest tool. We are now seeing (spring-summer 2014) a surprising amount of 2013 field-loss related volunteer corn from the 2013 harvest year, that could have been harvested earlier but drying costs seemed prohibitive. For crops that are displaying weak stalk strength and/or weather-type lodging, the EconoDri/VAL6 combos are another tool to start limited harvest instead of losing precious field yield losses because of prohibitive drying costs.  Even in a time of GMO crops that can be sprayed for volunteer old-crop, there is clearly competition between crops that can delay, retard or weaken the following crop plan.  This is a cost and expense related to the field losses that can be another downstream cost consideration for the EconoDri/VAL6 system. We have had discussions with producers who wondered if the EconoDri/VAL6 combos can work on continuous flow systems.  While the dry-air-to-grain principles should still apply, we know of no one who has gotten that far, though stacking or banking the EconoDri combos to create adequate dry air to a continuous flow fan (instead of a gas-fired higher humidity heat drying) is a project that we look forward to getting involved in.
